No round two for Jim Talent and Claire McCaskill

The doors are open for another Republican to challenge former State Treasurer Sarah Steelman for the U. S. Senate seat currently held by Democrat Claire McCaskill.
The man Ms. McCaskill beat five years ago, Jim Talent will not seek a rematch, according to a Kansas City Star article:

Talent, who lost to McCaskill in 2006, has not talked to reporters or issued a statement about his decision, but a formal announcement is expected any day.

The news comes as little surprise, given the interest of a Talent ally, former Missouri GOP Chairwoman Ann Wagner, in the 2012 race. Wagner has said she would not run against Talent for the Republican nomination.
