AZ-8 is a heavily Republican district with no Democratic roots (unlike PA-18), the GOP ran a good candidate with no scandals and who was a good fundraiser (also unlike PA-18), Trump won this district by 21 and Romney won it by 25, and the GOP saw great turnout last night. Yet, the Republican only won by 5 points. I think that the Republicans should be very concerned in November. If they can barely hang onto the most conservative of districts, even while running good candidates, their fortunes for the midterms look bleak.
