What if a state legislature engages in intentional partisan gerrymandering but it doesn’t work or might not work in the future? Has it violated the First Amendment?
In Benisek v. Lamone in 2011 the Maryland legislature needed to move about 10,000 voters out of the Sixth Congressional District to comply with “one-person one-vote.” It moved about 360,000 Marylanders out of the district and about 350,000 Marylanders in the district. As a result only 34 percent of voters were registered Republican versus 47 percent before redistricting.
Following the redistricting Democrat John Delaney defeated the incumbent Republican by almost 21 percent. But two years later in 2014 Delaney almost lost his seat even though his challenger didn’t live in the district and raised less money. Two years after that Republican Larry Hogan won the Sixth District beating his rival by 14 percent.
