Lordy, who knows!
You've got Jordan, a rabid Trumpinista if there ever was one and who has been endorsed by Doofus himself. And you've got Scalise, another Trumper, just not as 'vocal' about it. But he was 'endorsed' by Gaetz and that's enough to make my hackles rise.
The actual nominee is chosen by the GOP 'conference' so let's see how long it takes them to decide on Scalise vs Jordan. Or someone else, for that matter.
As far as the actual vote, the 'magic' number is 218 out of the 435, but if Reps vote 'present' or absent themselves it could be a smaller number. The GOP has 222 seats so they could easily elect based on a party line vote.
But 45 of them are 'Freedom Caucus' members. It goes without saying that they'll want the 'hardest line Trumper' they can find or demand hard line concessions before agreeing to nominate or vote the nominee. So will they 'hang the vote' by refusing to support a more moderate nominee? That's what happened with McCarthy and why it took 15 rounds.
Tune in Tuesday evening for the next episode of 'As the Stomach Turns'*, DC style.
*For our non-US friends that's a play on the title of an old US soap opera 'As the World Turns'.
