it seems that he has now changed his mind and will continue fighting the good fight in the house of representatives:
I had consulted with my family and reached the decision that I would fight for freedom from somewhere else. And there has been a reaction to that decision. The overwhelming reaction has been that people would like me to keep up the fight for freedom inside the U.S. House.
I am overwhelmed and humbled by the reaction of my colleagues. When the conservative movement asks you to stick around, that's a pretty tough request to turn down.
good for him. although if sen. mccain retires his seat, sen. shadegg does have a good ring to it.
