John McCain won the Republican nomination to seek a sixth Senate term in Arizona, defeating conservative primary challenger Kelli Ward Tuesday night.

Ward ran much of Donald Trump’s platform against McCain. She opposed the Iraq war and has been a firm critic of McCain’s immigration and foreign policies. She has raised his age as an issue — at 80, McCain is already two years older than his Senate predecessor Barry Goldwater at retirement — and described him as too weak to win in November. Many who cheered Paul Nehlen’s unsuccessful race against House Speaker Paul Ryan are now boosting Ward.
