Democrats upbeat as unpopular Trump imperils Republican midterm hopes

Polls show GOP candidates trailing Democrats in Senate races, and Republicans also struggling in House contests

Thirty days remain until the midterm elections, and Donald Trump and his Republican allies are pulling out all the stops to maintain control of Congress.

Super Pacs aligned with the GOP have already spent hundreds of millions of dollars on advertising and voter outreach in races expected to decide the majorities in the Senate and House of Representatives, and plan to spend even more before the election is over. The president, vice-president JD Vance, and other top Republicans are fanning out across the country to stump for vulnerable lawmakers.
