Lisa Ghelfi, a 58-year-old registered Republican in Arizona, voted for Donald Trump for president two years ago but has grown tired of his election-fraud claims. It is the main reason she voted for Democrats for governor, senator, secretary of state and attorney general this fall and plans to change her registration to independent. “Not allowing the election to be settled, it’s very divisive,” Ms. Ghelfi, a semiretired attorney from Paradise Valley, said of the 2020 race. “I think the election spoke for itself.” She said she voted for Republicans down-ballot who weren’t as vocal about election fraud or as closely tied to Mr. Trump, yet couldn’t support Arizona’s four major Republican candidates because they echoed Mr. Trump’s false claims.
