At the same time, election law experts said none of the lawsuits presented evidence of widespread fraud that could reverse Mr. Trump’s deficits. With Arizona added to Mr. Biden’s column on Thursday, he has comfortably won the election with at least 290 projected electoral votes, 20 more than needed for a majority. Two states, North Carolina and Georgia, remain undecided.
Bob Bauer, a leading Democratic elections lawyer and senior adviser to the Biden campaign, dismissed the notion of legislatures picking electors. “When all is said and done, you can’t stop the process from coming to the inevitable conclusion,” he said.
The idea of legislatures intervening for Mr. Trump gained currency in the days after Election Day, following months of Mr. Trump’s raging that the election would be “rigged,” a baseless accusation, although one embraced by many of his supporters.
On Nov. 5, as Pennsylvania’s gradual counting of mail-in ballots eroded Mr. Trump’s edge in the votes cast on Election Day, the Fox News commentator Sean Hannity suggested the results should be invalidated. Senator Lindsey Graham of South Carolina, a staunch Trump supporter, responded, “I think everything should be on the table.”
Earlier that day, Mr. Levin, the conservative radio host, had urged Republican state lawmakers to “get ready to do your constitutional duty,” writing in all capital letters on Twitter.
He was retweeted by the president’s son Donald Trump Jr. And Mr. DeSantis, the Florida governor, urged voters in Michigan and Pennsylvania, both with Republican-majority legislatures, to call lawmakers, who have it in their power to “provide remedies,” he said on Fox News.
