Trump's campaign swing boosts GOP candidates in key states.
Context
What happened: Trump campaigned in Arizona and Montana on the second day of a Western swing, rallying for Rep. Andy Biggs in Bullhead City and Aaron Flint in Montana's 1st District.
Key numbers: Elections are Nov. 3, under three weeks away. Trump won Arizona in 2016 and 2024, lost it in 2020.
Why it matters: The stops come as Republicans retreat from some battleground House races and Democrats raise money for candidates once seen as long shots, with Trump facing low approval ratings.
