Gerrymandering gave GOP 1 extra legislative seat

The AP analyzed the results of last fall's US and state House elections across the nation, examining the percentage of races lacking major party opposition and calculating state partisan advantages using a statistical method created to detect potential political gerrymandering.

The analysis showed that Idaho is among the top 10 states in the country with the biggest "efficiency gap", or the percentage of seats won by Republicans beyond what would be expected based on their statewide average share of votes.

Colorado Republicans cried foul when, after the last U.S. Census in 2010, the state Supreme Court approved a Democratic-drawn map reapportioning the state's 65 House seats.

The AP used their method to calculate efficiency gaps for all states that held partisan House or Assembly elections for all of their districts in 2016.

Republicans controlled both MI legislative chambers and the governor's office when the maps were redrawn in 2011. It cuts through three counties - and has three House seats, two held by Democrats. In that case, some voters from Wisconsin point out the efficiency gap in their state was 13 percent in 2012.

An analysis by The Associated Press shows election lines drawn by South Carolina Republicans after the 2010 Census may have slightly benefited the already dominating party. The Michigan House redistricting effort was led by then-state Rep. Pete Lund, who denied gerrymandering districts to favor Republicans.

Trump said Senate Democratic leader Chuck Schumer criticized the GOP bill before knowing what was in it. Only 12 Republicans aren't facing a Democratic challenger in November's election this year, compared to 44 Republicans who ran unopposed or faced only a third party challenger in 2015.

Democrats have long complained that Republican lawmakers drew unfair lines during the 2011 redistricting process, and say the proof is in plain sight. It also underscores years of legal battles in Texas over redistricting. Political scientists would expect a party to receive 2 percent more seats for every 1 percent over 50 they get in votes.

"In 2011, the gerrymander was the most artful that I've seen", Terry Madonna, director of the Center for Politics and Public Affairs at Franklin and Marshall College, told AP. The efficiency gap scores show Republicans picked up at least two excess seats each in MI and North Carolina.

The national Republican State Leadership Committee, the force behind the party's surge in state legislative elections, attributes its victories to candidates who better represent their communities.

President Donald Trump says he doesn't think congressional Republicans are "that far off" on passing a health overhaul to replace what he's calling "the dead carcass of Obamacare".
