Republicans made historic gains in the
2010 elections, flipping control of twenty legislative chambers across the country. Republicans made especially large gains in the South, winning control of a number of chambers for the first time since Reconstruction. Additionally, post-election party switching gave Republicans control of the
Louisiana House of Representatives. Three Southern states, Louisiana, Mississippi, and Virginia, did not hold regularly scheduled elections in 2010, but many took the 2010 results as a sign that Republicans would soon gain full control of these states as well. In February, Senator
Ezell Lee, who had been voting more and more frequently with Republicans, solidified his own switch to the party by filing to run for re-election as a Republican, flipping control of the chamber to the Republicans.
Redistricting The 2011 elections were the first held after the release of the results of the
2010 census; each of the four states up for election in 2011 attempted to draw new maps in accordance with the new population data. Republicans exercised full control of
redistricting in
Louisiana after having taken control of both chambers of the
legislature in late 2010 and early 2011. As the legislature showed no signs of resolving its impasse, federal courts took up the process. The NAACP sought new maps to remedy the population disparities that had grown between districts in the preceding decade, while some Republicans sought to hold the 2011 elections under the previous maps while passing new maps and holding new elections in 2012. The judges ruled to conduct the elections under the previous decades' maps, agreeing that redistricting was not required to take place until 2012. After the 2011 elections, the newly Republican-controlled legislature passed new legislative maps, but elections were not held again until 2015.
New Jersey In New Jersey, redistricting was controlled by a
bipartisan commission evenly-split between Democrats and Republicans. The commission was unable to reach a compromise on the maps and deadlocked, forcing the
Supreme Court of New Jersey to appoint an eleventh, nonpartisan commissioner. Commissioner Alan Rosenthal was unable to broker a compromise either, and he ultimately sided with the Democrats and voted for their proposal.
Virginia In Virginia, Democrats controlled the
Senate, while Republicans controlled the
governorship and the
General Assembly. To avoid a deadlock in the
redistricting process, the leaders of both chambers reached a "gentleman's agreement" that the party in control of each chamber would draw their own maps without interfering with the others' map. Despite this, Republican governor
Bob McDonnell vetoed the redistricting proposal, objecting to the Democratic-drawn Senate map. The legislature later passed a compromise bill, which McDonnell signed.
Other party switching Like during the immediate aftermath of the 2010 election, a large number of Democratic state legislators, primarily from the
South, switched to the Republican party. This included further switches in the
Louisiana House of Representatives, which gave Republicans a true
majority in the chamber, allowing them to bypass both the Democrats and the four
independents in the chamber to pass legislation.
