A federal judge Thursday cast doubt on President Donald Trump’s lawsuit that seeks to overturn Joe Biden’s win in Wisconsin, saying siding with Trump would be “the most remarkable ruling in the history of this court or the federal judiciary.”

Trump is pursuing extraordinary attempts to overturn Biden’s win with a pair of lawsuits in Wisconsin, in federal and state courts. Hearings on both cases were scheduled for Thursday. In the state case, Trump wants to disqualify more than 221,000 ballots and in the federal case he wants to give the GOP-controlled Legislature the power to name Trump the winner.

At the beginning of arguments in the federal case, U.S. District Judge Brett Ludwig marveled at Trump’s request.

“It’s not lost on me that this is a political case, obviously, and that the relief that’s been requested, if that relief were granted, this would be a most remarkable proceeding and probably the most remarkable ruling in the history of this court or the federal judiciary,” Ludwig said.

Ludwig, a Trump appointee, had previously called the Trump request “bizarre” and “very odd.”

Trump’s attorney Bill Bock argued that the election wasn’t run properly and that the risks of voter fraud were increased because ballot drop boxes were not staffed, voting by mail was widely used and voters who said they were indefinitely confined were allowed to cast absentee ballots without showing a valid photo ID.

“In what what area of American life is it more important that the rules be followed and the playing field be level than in an election for president of the United States?” Bock said.

Trump’s attorneys are urging the courts to act quickly so he can appeal any adverse ruling before members of the Electoral College meet on Monday and cast Wisconsin’s 10 votes for Biden. Attorneys for Gov. Tony Evers and the bipartisan state elections commission say the cases are without merit and should be dismissed.

On Wednesday, a federal judge in Wisconsin dismissed another lawsuit filed by the chairman of the La Crosse County Republican party that argued there was massive fraud that warranted the court declaring Trump the winner.  Similar lawsuits, all filed by Trump’s former campaign attorney Sidney Powell, have been dismissed in Arizona, Georgia and Michigan.

Powell appealed the Wisconsin ruling on Thursday to the 7th U.S. Circuit Court of Appeals.

Trump’s state lawsuit made Wisconsin the only state that missed Tuesday’s safe harbor deadline, which means Congress has to accept the electoral votes that will be cast Monday and sent to the Capitol for counting on Jan. 6. Missing the deadline won’t deprive Wisconsin of its 10 electoral votes.
