Redistricting Scorecard

Forty states have already completed the decennial redistricting process. Another seven states have at-large districts and do not redraw lines. That leaves three states that still need to produce new maps before the 2012 elections.

State Date Completed Seat Gain/Loss Number of Districts in 2012 What Happened Member Vs. Member Voting Rights Act Preclearance
Arkansas April 14, 2011 0 4 Democratic line drawers extended the boundaries of the 4th district, the state's only Democratic-held seat, further to the northwest. More Republicans moved into the three other GOP districts. no no
Louisiana April 14, 2011 -1 6 The Republican-drawn map effectively eliminates the 3rd district and solidifies other GOP territory; the majority-minority 2nd now stretches from New Orleans to Baton Rouge. Charles Boustany (R) vs. Jeff Landry (R)* Cleared Aug. 1, 2011
Iowa April 19, 2011 -1 4 Each of the state's four quadrants is now a separate district. Tom Latham (R) vs. Leonard Boswell (D) no
Missouri May 4, 2011 -1 8 Two Democratic-held districts in St. Louis were combined into one predominately African-American district where Rep. Russ Carnahan will challenge Rep. William Lacy Clay in the primary. William Lacy Clay (D) vs. Russ Carnahan (D) no
Indiana May 10, 2011 0 9 Republicans made the Democratic-held northern 2nd district more favorable to the GOP and shored up the Republican-leaning 9th districts. A few competitive counties in Southern Indiana were shifted into the 8th district, effectively making it slightly more Democratic. no no
Oklahoma May 10, 2011 0 5 Only minor tweaks were made to district lines. no no
Texas May 18, 2011 4 36 A federal court in San Antonio ordered a new interim map that gave the GOP a 25-to-11 advantage. Meanwhile, judges in the U.S. District Court for the District of Columbia are expected to rule soon whether to give approval to the original Texas map passed by the Legislature. It's highly unlikely that court will grant preclearance, which means Texas lawmakers will probably take another stab at drawing the map next year. no awaiting
Nebraska May 26, 2011 0 3 Only minor changes. no no
Alabama June 8, 2011 0 7 There is an increased GOP tilt in Republican-held districts; the map strengthened the Democratic majority-minority 7th district. no Cleared Nov. 21, 2011
Illinois June 24, 2011 -1 18 Democrats drew new lines that could result in five GOP Members losing their seats. Republicans lost their lawsuit challenging the map. Adam Kinzinger (R) vs. Don Manzullo (R) no
Oregon June 30, 2011 0 5 The biggest changes came in the 1st district and Rep. Kurt Schrader's (D) 5th district, both of which lost portions of Portland's Multnomah County. The changes aren't drastic, but the new lines could mean more competitive races for Republicans. no no
North Carolina July 27, 2011 0 13 The new map double-bunked two Democratic pairs while increasing the Republican lean of four already vulnerable Democratic Members. It also strengthened the GOP tilt of freshman Rep. Renee Ellmers' seat. Rep. Brad Miller retired after deciding not to engage in a Member-vs.-Member race against Rep. David Price. no Cleared Nov. 1, 2011
South Carolina Aug. 1, 2011 1 7 The new 7th district was added to the northeastern part of the state; it strengthens the districts of Reps. Joe Wilson (R), Mick Mulvaney (R) and James Clyburn (D). no Cleared Oct. 28, 2011
Michigan Aug. 9, 2011 -1 14 Republicans drew Reps. Gary Peters and Sander Levin into the same district, but Peters opted to challenge Rep. Hansen Clarke in the Democratic primary instead. GOP mapmakers substantially strengthened the GOP lean of the district of Rep. Thaddeus McCotter (R) while also shoring up Republican Reps. Dan Benishek and Tim Walberg. Gary Peters (D) vs. Hansen Clarke (D) no
Wisconsin Aug. 9, 2011 0 8 The Republican-drawn map shores up Rep. Sean Duffy's 7th district. no no
California Aug. 15, 2011 0 53 The new independent commission totally revamped the map, and Democrats are assured of picking up at least a couple of seats. There will be several Member-vs.-Member races and far more competition (in 2012 at least) than in the last decade. Janice Hahn (D) vs. Laura Richardson (D) Brad Sherman (D) vs. Howard Berman (D) no
West Virginia Aug. 18, 2011 0 3 The map remains nearly identical with one county moving from the 2nd district to the 3rd. no no
Georgia Sept. 7, 2011 1 14 While shoring up GOP districts С and moving many geographically С the GOP-controlled Legislature put Rep. John Barrow's (D) political future in danger. They drew him out of his district and made it substantially more Republican. The extra district allotted to the Peach State during reapportionment was placed in the northeast portion of the state and numbered as the 9th. no Cleared Dec. 23, 2011
Ohio Sept. 26, 2011 -2 16 Republicans shored up most of their freshman Members but moved three Democrats and three Republicans into three districts: Reps. Dennis Kucinich (D) and Marcy Kaptur (D), Reps. Betty Sutton (D) and Jim Renacci (R), and Reps. Mike Turner (R) and Steve Austria (R). Austria declined to seek re-election instead of face Turner. Republicans also drew a new Democratic, open-seat district in downtown Columbus. Marcy Kaptur (D) vs. Dennis Kucinich (D) Betty Sutton (D) vs. Jim Renacci (R) no
Hawaii Sept. 26, 2011 0 2 The 2nd district decreased in size some, but Democrats still have the edge in both districts. no no
Maine Sept. 28, 2011 0 2 While the new map moves Waterville and Winslow into the 1st district and 11 municipalities into the 2nd, Maine's two districts remain almost identical politically. no no
Idaho Oct. 18, 2011 0 2 The line separating the state's two districts was moved three miles west, but neither GOP incumbent will be affected much. Boise's Ada County, the largest in the state, will still be split almost exactly in two, and the GOP is favored to hold both seats. no no
Maryland Oct. 20, 2011 0 8 The 6th district was dramatically altered, endangering Rep. Roscoe Bartlett (R) and likely handing that seat to Democrats. Rep. Donna Edwards' (D) 4th district lost portions of more liberal Montgomery County and gained more conservative Anne Arundel. As a result, Edwards is facing a serious primary challenge in her safe Democratic seat. no no
Utah Oct. 20, 2011 1 4 Republicans have a good chance of winning all four districts after the GOP-controlled Legislature split up Salt Lake County into three districts. Rep. Jim Matheson (D) could run in a couple different districts, but neither is a great option. no no
Nevada Oct. 27, 2011 1 4 Now with one of the state's three seats, under the new map С and with an additional district С Democrats are looking at possibly winning three of four next year. There's one Safe Republican district, two Safe Democratic districts and one Tossup that leans Democratic. no no
Massachusetts Nov. 21, 2011 -1 9 The state's western district, represented by retiring Rep. John Olver (D), was combined with the Springfield-based district represented by Rep. Richard Neal (D). Other Democratic incumbents were shored up with the exception of Rep. John Tierney (D), whose district saw the addition of two towns that Sen. Scott Brown (R) carried in 2010 and part of one town that voted for Brown. no no
Colorado Dec. 5, 2011 0 7 A court implemented a Democratic-friendly map that shores up Rep. Cory Gardner's (R) district to make it more safe for the GOP. Rep. Mike Coffman (R), who has held a safe Republican seat, will run for re-election in swing territory. Rep. Scott Tipton's 3rd district remains competitive. no no
Pennsylvania Dec. 22, 2011 -1 18 Republican mapmakers shored up GOP freshmen in the new map, especially Rep. Lou Barletta. But despite the GOP's best cartography efforts in southeastern Pennsylvania, a few Republican House Members (Rep. Mike Fitzpatrick and Rep. Patrick Meehan) still represent competitive districts around Philadelphia. In southwestern Pennsylvania, Republicans drew Democratic Reps. Mark Critz and Jason Altmire into the same GOP district. Jason Altmire (D) vs. Mark Critz (D) no
New Jersey Dec. 23, 2011 -1 12 The Independent tie-breaker on the N.J. Redistricting Commission chose a map that put Rep. Steven Rothman (D) into Rep. Scott Garrett's 5th district. Rothman opted to run against Rep. Bill Pascrell (D) in the safe Democratic seat's primary. Bill Pascrell (D) vs. Steven Rothman (D) no
New Mexico Dec. 29, 2011 0 3 A state judge approved a plan that makes no significant changes to the lines or competitiveness of the state's three districts. The open, Albuquerque-based 1st remains the most competitive district and the one to watch in 2012. no no
Mississippi Dec. 30, 2011 0 4 The state Legislature didn't act, so the federal court, which drew lines in 2002, adjusted the map for population growth. no Not needed because the map was drawn by the court
Tennessee Jan. 26, 2012 0 7 The state Legislature solidified the current districts, likely ensuring a seven Republicans-two Democrats split for the foreseeable future; the map substantially shored up GOP Rep. Stephen Fincher's 8th district. no no
Arizona Jan. 17, 2012 1 9 After a rancorous process, an independent commission drew a map that enraged Republicans. Most of the district numbers changed in the process. Rep. Paul Gosar (R) opted to leave his current Tossup district to run in the 4th; Rep. Ben Quayle (R) was drawn into the Tossup 9th and opted to run against fellow Republican David Schweikert in the 6th. The new map has four Safe Republican seats, two Safe Democratic seats and three Tossups. Ben Quayle (R) vs. David Schweikert (R) awaiting
Virginia Jan. 25, 2012 0 11 Republicans won control of both legislative chambers in November, then passed an incumbent-protection plan in January that gives the GOP a strong opportunity to control eight of the 11 seats for the next 10 years. no awaiting
Washington Feb. 7, 2012 1 10 The new 10-district map approved by a bipartisan redistricting commission on New Year's Day made Republican and Democratic incumbents safer, gave Democrats a favorable new district and made Rep. Jay Inslee's (D) open seat north of Seattle the most competitive in the state. no no
Rhode Island Feb. 8, 2012 0 2 The Democratic-controlled statehouse passed a map that shifted Democratic voters from the 1st district to the 2nd district. The move helps Rep. David Cicilline (D), who could face a tough re-election this year. no no
Kentucky Feb. 10, 2012 0 6 The state Legislature passed an incumbent-protection map, which shored up Rep. Ben Chandler's (D) seat. no no
Connecticut Feb. 10, 2012 0 5 Because the redistricting commission was unable to come to a consensus on a new map, the state Supreme Court tasked an independent expert called a "special master" to draw up a map that took a minimalist approach to changing lines from the previous decade. no no
Florida Feb. 16, 2012 2 27 Republicans shored up their substantial advantage in the Congressional delegation, but the GOP-drawn map left some districts vulnerable to Democratic pickups, including Rep. Steve Southerland's panhandle 2nd district and the now-open south coastal 22nd district. (GOP Rep. Allen West, who currently represents the 22nd, decided to run in the 18th.) A lawsuit from Democrats is pending in state court. The state party alleges that the Congressional map violates new Fair Districts state constitutional standards, which prohibit maps from being drawn "with the intent to favor or disfavor a political party or an incumbent." A court ruling, if judges see the suit as valid, which remains to be seen, would likely force changes to Orlando-area districts, especially the 10th, where freshman Rep. Daniel Webster (R) is the incumbent. Rep. Sandy Adams (R) vs. Rep. John Mica (R) awaiting
Minnesota Feb. 21, 2012 0 8 After the state Legislature and Gov. Mark Dayton (D) were unable to come to agreement, a panel selected by the state Supreme Court chief justice drew a map that left the lines largely unchanged. Rep. Michele Bachmann (R) was drawn out of her 6th district but said she would still run for re-election in that seat. no no
