The Supreme Court has ruled 5-4 on Thursday that they are leaving the issue of partisan gerrymandering at the state level.

"The court holds that partisan gerrymandering claims present political questions beyond the reach of the federal courts," Chief Justice Roberts wrote.

Part of the issue considered by the justices was whether Maryland state Democrats drew unconstitutional boundaries with sinister goals.

The judges said Democratic state officials unconstitutionally drew the district’s boundaries with a goal of diminishing Republican influence.
