Republicans initially tried to redraw the lines to divide Maine's two congressional districts into an east-west configuration instead of north-south.
The AP scrutinized the outcomes of all 435 U.S. House races and about 4,700 state House and Assembly seats up for election a year ago using a new statistical method of calculating partisan advantage created to detect potential political gerrymandering.
The victor in more than 40 percent of all state Assembly or House races last November ran unopposed by a candidate from the other major party. But in the end, Maine's districts remained much the same as they had been even as gerrymandering produced odd-shaped districts in other states.
"Republicans have done a good job of targeting those areas and getting good candidates and putting a lot of money into marginal districts, which they tend to win", he said. The data also doesn't identify any particular districts where the legislative map might give Republicans a boost. Virginia is a swing state where Democrats have won, often by slim margins, every statewide office since 2009.
The amount of partisan advantage favoring Missouri Republicans was fairly typical when compared with other states.

When asked about the allegations, Bernie declared, "This implication came from Donald Trump's campaign manager in Vermont". Two former Burlington College trustees said they were also contacted by attorneys representing Sanders, wife of U.S.
Democrats held a partisan advantage in races in Maryland, Colorado, and Nevada, the analysis found, where legislative districts were re-drawn by a Democratic-majority legislature, a Democrat-led commission and by a court, respectively.
"The model may say one thing but the truth is Republicans hold 17 House seats won by Hillary Clinton in 2016".
Torr said he plans to reintroduce the bill in the next legislative session ahead of the upcoming redistricting.
In Pennsylvania, Republicans won 13 of the 18 congressional seats a year ago, three more than would be expected based on the party's vote share, according to the AP analysis. Sometimes delegates wanted the boundaries changed to draw out a potential primary challenger, Jones said.
The map, drawn in 2011, was called "the worst gerrymander in modern Pennsylvania history" by Franklin & Marshall College political scientist G. Terry Madonna and is now the subject of its first court challenge, filed earlier this month by the League of Women Voters and 18 registered Democratic Party voters. Even taking those into consideration, however, AP's analysis found that gerrymandering handed the GOP a decisive advantage. Republicans may have won an extra congressional seat over what would have been expected based on the average vote share around the state that shows a large so-called "efficiency gap".
The efficiency gap method was designed by University of Chicago Law professor Nick Stephanopoulos and researcher Eric McGhee at the Public Policy Institute of California. The U.S. Supreme Court said it will hear that case, potentially affecting voting across the U.S.
