Chuck Schumer dumped $9 million into an Iowa Democratic primary based on a claim that turns out to be wrong, which is bad for Democratic donors and embarrassing for the party establishment.

• Schumer is backing state rep Josh Turk over state senator Zach Walls because Turk said he would support Schumer as leader.
• The pitch for Turk is that he flipped a Republican seat, making him more electable in Iowa.
• He did not flip a Republican seat. Iowa redrew its districts after the census, and Turk actually represents Council Bluffs, a Democratic-leaning area that has split its ticket since the 1960s.
• The error appears to come from ChatGPT and Wikipedia, and got repeated by The Atlantic, NBC News, NPR, and the super PAC's own top strategist.
• Vote Vets ads also blur the line between Turk, who was born with spina bifida, and an actual veteran, opening him up to a stolen valor attack from Republicans.

Outlook: The primary is June 2, and the race is reportedly still close despite the $9 million, which undercuts the whole electability argument.
