He’s withdrawing tomorrow.
He's being forced out by a contrived situation IMO.
Is the GOP going to support the new candidate or will this be a repeat just like in Illinois after Ryan "withdrew" where the Republican Party wound up not supporting the person who finally had the courage to step up to the plate? We can all see now where that lack of support got us. Time will tell.
I wish the person stepping up to the plate good luck, for if history is something to be learned from they're going to need all the luck (and support) they can get!
