Trump's approval has fallen to a record low and Republican candidates are backing away from him, which is bad news for the party's chances in the midterms.

• Trump's approval sits at 32%, and support inside his own party has slipped below 80% from near-universal backing.
• Democrats now lead Republicans by 8 points in generic polling, the widest gap recorded this term.
• The main causes are the Iran war, high gas and grocery prices, and tariffs that hurt farmers and ranchers.
• At least seven Republican House candidates have scrubbed Trump mentions from their websites, including Byron Donalds in Florida.
• Republican Senate seats in Iowa, Kansas, Mississippi, Arkansas and South Carolina are suddenly in play, forcing the party to spend money in states it thought were safe.

Outlook: Republicans face an uphill fight to hold Congress unless prices fall and the Iran war ends soon.
