I am surprised at Sanchez’s low level of support and this is from a Republican polling firm. I agree that he should stay where he is for now. Perhaps many note that he’s only held his current office for four months.
Ideologically, Heather Wilson is satisfactory, if nothing spectacular. She’s no Dede Scozzafava.
I think he could really put a dent in her support by attacking hard from the right but such a divisive primary wouldn’t be good.
