Of course it’s allowed, it’s a floor election in which every congressperson votes - but the Democrats have been voting as a bloc for Jeffries so the only thing that’s mattered so far is the divided Republican vote.

But in practice there is no way that any of them will flip to McCarthy. There is exactly one thing that the Democrats and the rebels agree about - and that is Kevin McCarthy’s unsuitability for the job.

Less unlikely is that a half-dozen Republicans will cross the aisle to support a Democrat - Jeffries would step aside for that.
