I’ll disagree with you about Kasich. He’s a pro-amnesty big government liberal. He could easily be the elite backstabbers “plan B” if allowed to stay around and gain some traction before his record gets the scrutiny it deserves.
Kasich has 3% support, consistently below even Christie. Until I see something more interesting from him, I'm not worried about him as Plan B because he's not likable or effective on the campaign trail.
