I’d love to see McIntyre switch parties!
McIntyre is my Congressman. As noted upthread, he's basically a good guy as far as conservatives are concerned. However, even if he wanted to there's no way he could switch parties and keep his seat. The North Carolina Democrat machine has this state and it's people by the throat and would destroy him if he did that. They'd replace him with a pliable party hack they could be certain to control as an object lesson to any other would-be "traitors" to party loyalty.
As others have stated, term-limits are not the solution, re-educating the American people is.
