Rep. John Shadegg (R-AZ), a stalwart conservative who ran unsuccessfully for majority leader and minority whip in 2006, has reversed his decision from last week to retire. Shadegg's decision was seen by many as a sign of lost confidence among the House GOP, and many of his fellow Republicans asked him to stay on.

"I am overwhelmed and humbled by the reaction of my colleagues," Shadegg told National Review. "When the conservative movement asks you to stick around, that's a pretty tough request to turn down."
