Trump Legal Efforts Falter in Bid to Undo Biden's Presumptive Victory Masood Farivar U.S. President Donald Trump's legal battles to undo Democrat Joe Biden's presumptive victory in the Nov.3 presidential election faltered Friday as courts pushed back against allegations of voting irregularities and fraud. A Michigan judge rejected a bid by Republican Party supporters to prevent the certification of election results in the predominantly Democratic Detroit area, undercutting the prospects of a similar lawsuit filed by the Trump campaign. In Pennsylvania, another judge dismissed a series of Trump lawsuits challenging the validity of several thousand mail-in ballots, while in Arizona the Trump campaign dropped a lawsuit over the election results, acknowledging that Biden's lead was too large to surmount. The three states are among a half dozen where Trump and his supporters launched legal challenges to the results in the wake of projections that Biden had decisively won the election, with well in excess of the 270 Electoral College votes necessary to claim victory. Legal challenges Trump, who had yet to concede the election to Biden as of Friday evening, has engaged in a battle of dubious legal challenges and unfounded claims on social media in a long-shot bid to overturn the election results. Taken together, the latest developments bode poorly for Trump's chances of winning the election with unsupported claims of rampant fraud, according to experts. "I think these lawsuits can best be understood as ways in which the president is messaging to his base that he is contesting the results of the election and is continuing to try to fight to overturn the results," said Louis Caldera, distinguished adjunct professor of law at the American University Washington College of Law. He added that this was "not a serious effort to actually change the voting outcome in sufficient numbers of states to be able to collect the Electoral College votes that it would be necessary for him to win the election." The Michigan lawsuit, filed Sunday by a conservative group, sought to have hundreds of thousands of ballots in Wayne County tossed because of alleged fraud and voting irregularities. According to unofficial results, nearly 73% of the 565,484 votes in Wayne County went to Biden. The petitioners asked a judge to order an independent audit and an entirely new election. But Chief Judge Timothy Kenny of the 3rd Circuit Court in Wayne County ruled that the allegations of "sinister fraudulent activities occurring both openly '¦ and under the cloak of darkness" were contradicted by other poll challengers and officials, including a former "highly respected" state election official. Stopping the certification process now would amount to "an unprecedented exercise of judicial activism," Kenny wrote in his order, while conducting an independent audit would delay the vote tabulation and "undermine faith in the electoral system." .
