On paper, Arizona has at least two of the more compelling pick-up opportunities in the U.S. House of Representatives this year.
But as the congressional campaigns passed Labor Day, the parties and their allies had only begun to invest in shaping the tone and stakes for what voters must settle on Nov. 3.
National Democrats had spent $478,000 in the race to hold onto the 1st Congressional District seat held by Rep. Tom O’Halleran, D-Ariz. Neither of the national party’s House campaign arms had spent on the 6th Congressional District seat held by Rep. David Schweikert, R-Ariz.
