Rep. Shadegg to Retire

Add yet another name to the GOP retirement list. Arizona Rep. John Shadegg (R) is on the verge of announcing that he will not run for re-election, according to Republican sources.

Shadegg is in his 7th term in the House and is the former chairman of the conservative Republican Study Committee. He served briefly as House GOP Policy Chairman and then lost a bid for House Majority Leader in 2006.

Shadegg will be the 22nd House Republican to announce his retirement this cycle. Another three GOP lawmakers are running for other offices.

Shadegg's Phoenix-area 3rd district should stay in the Republican column. President Bush won it with 58 percent of the vote in 2004.

UPDATE: Here's Shadegg's statement announcing his decision.
