A rewrite of Pennsylvania's congressional map is headed to Gov. Tom Wolf's desk following a party-line state Senate vote on Monday. But with Wolf having already vowed to veto the proposal, the move is nearly guaranteed to put the courts in charge of determining the state's new district lines.

Monday's 29-20 vote in favor of the Republican-backed plan, which nonpartisan analysts say has a clear GOP advantage, followed what Senate Majority Leader Kim Ward (R., Westmoreland) described as a failed effort by senators to find a compromise, Spotlight PA and Votebeat report.

"We can't agree," she said, adding, "The governor is going to veto anything that is not what he produced, and the courts will wind up drawing maps."

State Sen. Sharif Street (D., Philadelphia) said the map was not the result of a bipartisan process and agreed that it "will most assuredly get vetoed."

THE CONTEXT: Anticipating the impasse, two groups of Pennsylvanians asked Commonwealth Court to intervene in December.

The court set a Jan. 30 deadline for Wolf and lawmakers to finish the map, while also asking the citizen petitioners, Wolf, Republican and Democratic lawmakers, and other approved parties to submit their own proposals.

The court will hold hearings on those maps this Thursday and Friday. It could pick one as soon as Sunday. A lawyer for one of the petitioner groups said it's likely the ruling will be appealed to the state Supreme Court. 

Meanwhile, a Wolf administration-set deadline came and went on Monday without the new political maps deemed necessary to keep the May primary on track, sowing confusion among voters, candidates, and administrators.
