After the U.S. Supreme Court rejected an attempt by the Pennsylvania GOP to restore the state's "insanely gerrymandered" congressional map on Monday, one Republican decided that the next rational course of action would be to launch an impeachment campaign against the five state justices who deemed the map unconstitutional—a move critics denounced as a "remarkable" attempt to subvert democracy.

The effort was spearheaded by Republican Pennsylvania state Rep. Cris Dush, who sent a memo attacking the state Supreme Court's 5-2 ruling last month that said the GOP-drawn districts "clearly, plainly, and palpably" violate the state constitution. Many analysts agreed with this interpretation, calling the map one of the most extreme partisan gerrymanders in the nation.

Instead of obeying the court's order to redraw the map ahead of the 2018 midterms, Dush on Monday urged his colleagues to co-sponsor legislation to remove the five Pennsylvania Supreme Court justices who struck down the map.

"The five justices who signed this order that blatantly and clearly contradicts the plain language of the Pennsylvania constitution, engaged in misbehavior in office. Wherefore, each is guilty of an impeachable offense warranting removal from office and disqualification to hold any office or trust or profit under this Commonwealth."

While experts characterized the Pennsylvania GOP's legal arguments for restoring the gerrymandered map as "frivolous," many reacted with alarm to Dush's memo, calling it a "serious threat" because Republicans—thanks to aggressive gerrymandering—hold a strong majority in the state legislature.

"This is a dangerous disregard for the rule of law by Pennsylvania Republicans," voting rights expert Stephen Wolf argued on Twitter Monday. "Impeaching judges because one disagrees with a court decision that strengthened democracy is a classic move of authoritarian regimes."

Other commentators expressed their agreement with Wolf, calling the impeachment push further evidence that "the Republican Party does not believe in democracy."
