Why would a Democrat back the Republican two days before the vote?

Two days before the midterms, Democratic congresswoman Haley Stevens stood in a church in Detroit beside Republican Mike Rogers. She had pressed El-Sayed to denounce an ad that, she says, blames Israel for grocery prices, and she says his campaign rests on hate.

El-Sayed had told her she was no longer welcome, and she agreed: I don't belong in Abdul's campaign.

Party chair Curtis Hertel accused her of abandoning the party. El-Sayed said she wants to reopen a primary result. His campaign announced it raised 1.2 million dollars in the first four hours after her endorsement.

A RealClearPolling estimate cited by one outlet puts El-Sayed nearly 4 points ahead of Rogers, and Michigan is among the states likely to decide Senate control.
