Republicans in Arizona and other parts of the country have handed Democrats an advantage in balloting due to former President Donald Trump's false claims about the risks of mail voting. Conservative conspiracy theorists urged GOP voters to wait until Election Day before casting their ballots and spun tales about how such a strategy would prevent Democrats from rigging voting machines to steal the election.

Democratic Sen. Kyrsten Sinema of Arizona announced Friday that she has registered as an independent, but she does not plan to caucus with Republicans, ensuring Democrats will retain their narrow majority in the Senate.
