*cricket noise*
I’ve said from day one, the GOP will do something underhanded to yank the nomination from Trump if it kills them and the party. They made him sign a pledge to support the party nominee, but they have no intention of supporting him when it turns out he fooled them and got it anyway.
He’s also pulling voters form Democrats and Independents, he’s been setting the narrative and staying ahead of their game all along, I think if he did decide to go 3rd party if they screw him, he could probably still win. His current base of supporters will stay with him no matter what, if he runs 3rd party I don’t think a thing will change, he will still pull a lot of voters who wouldn’t admit it if they were asked, but when the curtains close, it’s a different story.
