This Will Not Pass: Trump, Biden, and the Battle for America's Future by Jonathan Martin and Alexander Burns:
It was not only in Georgia that Trump was testing the mettle of Republican officials with demands that they engage in a version of election tampering. He may not have been a sophisticated political strategist, but the president recognized he needed to flip several states to win the election, all of which Biden had carried by far more than his 11,779-vote margin in Georgia.
The absurdity of that task did not deter Trump from attempting it. One November 20, he summoned the Republican leaders of the Michigan legislature to the White House. The president wanted to speak with them in the Oval Office about the outcome of the presidential race there and apply pressure on them to block Michigan’s sixteen Electoral College votes from going to Biden.
It was precisely the scenario that Gretchen Whitmer and other Michigan Democrats had anticipated the previous fall, before Biden carried the state by more than 150,000 votes. Should the state legislators attempt to appoint a separate slate of pro-Trump electors, in defiance of the popular vote, Whitmer was prepared to name another slate consistent with the will of the people.
