Signs point to a rough midterm election for Republicans, with even longtime Trump voters starting to turn away.

• Polls show unexpected trouble for Republicans in deep-red Mississippi, where a Black Democrat now has a real shot at a Senate seat thanks to high Black voter turnout and some white voters switching sides.
• Longtime Trump supporters in swing states say they regret backing him, pointing to his trade war with Canada and general chaos as reasons they're reconsidering.
• Senate control is a tossup, with Republicans needing to avoid losing more than three seats; Democrats are even spending money in unlikely places like Mississippi, while Republicans are playing defense in Minnesota.
• A Michigan voter is urging Black voters not to sit out the election, warning that Senate control decides who replaces aging Supreme Court justices and could shape the Court for decades.
• A separate discussion of rising child-rearing and healthcare costs is dominating the news cycle at the same time, highlighting the economic squeeze many people feel regardless of politics.

Outlook: With just over a week left, momentum appears to be shifting against Republicans in several unexpected states, which could cost them Senate control if the trend holds.
