This just in, from John Shadegg's website:
I am today announcing that, while I will serve out my current term in the U.S. House of Representatives, I will not be a candidate for re-election to Congress. Representing the people of Arizona in the House has been one of the greatest privileges of my life. And, while it would be difficult to leave this position at any time, it is particularly hard to do so now with the challenges we face as a nation, but it is necessary for me to do so.
While representing the people of Arizona in the House was one of my goals in life, it is not the only one. After 16 years it is time for me to take my life in a new direction and to pursue my commitment to fight for freedom in a different venue.
Shadegg's announcement not to seek reelection in 2010 brings the total number of Republican retirees to 14. On the other side of the aisle, 10 Democrats in the House have decided not to seek reelection.
