This is what happens when there isn’t a Tom Delay type running things, cracking the whip, keeping people in line, and keeping everyone’s eyes on the ball. You can’t run a campaign by committee. No campaign should accept this.
You nailed it, the R party is in disarray, there’s no leadership, and the members at the top are like rats deserting a sinking ship and looking out for themselves. You’re right, there’s no Delay-type to crack a whip on them and stop this nonsense.
