In Michigan’s Macomb County, the Republican head of the board that will certify November’s election results called on former U.S. President Donald Trump to fight to stay in power after his election loss in 2020.

In North Carolina’s Henderson County, a Republican election board member emailed legislators in August to claim, without evidence, that Democrats were flooding the state with illegal votes.

And in Pennsylvania, considered a must win for both Trump and his Democratic rival, Vice President Kamala Harris, Republican officials in six counties have voted against certifying results since 2020.

Four years after Trump tried to overturn his election loss, his false conspiracy theories about voter fraud have become an article of faith among many Republican members of local election boards that certify results. Their rise raises the chances that pro-Trump officials in multiple jurisdictions will be able to delay or sow doubt over the Nov. 5 presidential election if Trump loses.
