PHOENIX (AP) – Former Arizona Sheriff Joe Arpaio’s announcement that he’ll run for the Senate seat being vacated by fellow Republican Jeff Flake potentially pits two conservative, pro-Donald Trump candidates against each other and could create an opening for a more moderate GOP contender to take the seat.

Arpaio made the announcement Tuesday, injecting new uncertainty and attention into the race that’s already among the year’s most-watched.

If Arpaio follows through and files his candidacy papers, the race could feature one of President Trump’s most vocal supporters trying to replace one of his fiercest detractors. Flake has constantly criticized the president.

Until now, the Republican front-runner in the race has largely been considered to be Kelli Ward, a former state senator. Arpaio’s entry could hurt her chances.

“I think he would just suck up most of her support. He is a much more prominent and visible person, he’s been around so long,” said David Berman, a senior research fellow at Arizona State University’s Morrison Institute of Public Policy. “Most people who like Trump generally gravitate toward Arpaio.”
