A viral on-air mishap has ended up boosting attention on the Michigan Senate race, which is bad news for Republican candidate Mike Rogers.

• Cenk Uygur's chair collapsed mid-argument on Piers Morgan's show while he was attacking Mike Rogers over the Iran war; a loose screw, not the internet's favorite theories.
• The argument itself: Rogers has pushed for war with Iran for 20 years and took heavy money from drug and health insurance companies, then blocked drug price negotiation.
• Uygur says the media ignores all of that and instead attacks Democrat Abdul El-Sayed by tying him to Hasan Piker's past comments about America — guilt by association.
• Ronna McDaniel, the former Republican Party chair, was on the other side of the debate, calling Uygur too aggressive.
• The clip spread far enough that more people ended up hearing the case against Rogers than would have otherwise.

Outlook: Expect the Michigan Senate race to keep being fought over Israel, the Iran war, and who counts as "pro-America" rather than over the candidates' own records.
