I don't think a "conservative" takeover is possible, or likely to change anything. The committee chairs would still be controlled by the "moderates". The only change would be a conservative majority leader. I am not sure how much that would help, but either way I don't see it happening anytime soon.
Also, I think Staton will have a tough race ahead of him. Even so, this would be ahuge win for the GOP if they can manage a win here.
