According to TheEngineer:
Shadegg, John [R-AZ]
Rep. Shadegg is F rated in my Congressional guide, as he cosponsored both HR 4411 and HR 4777. Shadegg announced that he would not be a candidate for reelection. However, ten days later, he announced that he would seek reelection. The Democratic nominee, tax attorney Bob Lord, outraised Shadegg in the first quarter of 2007 and has more cash on hand than Shadegg. Independent candidate Annie Loyd and Libertarian Michael Shoen are also running.
