Cillizza also points out that Republicans are not exactly swarming toward the only announced candidate, former State Treasurer Sarah Steelman:
Former state Treasurer Sarah Steelman is the lone Republican in the race, but she's got no shortage of potential GOP opponents, including Rep. Sam Graves, former state party chairwoman Ann Wagner and former congressional candidate Ed Martin. What that suggests is that many aren't quite ready to embrace her as their next big Senate candidate. And if Talent bows out, these candidates will feel free to enter the race at will.
But that could be changing. Politico's Dave Catanese (who broke the news Tuesday) smartly points out that Sen. Roy Blunt's (R-Mo.) former chief of staff has penned a fundraising letter for Steelman. (Steelman, you may recall, opted against challenging Blunt in a primary last cycle.)
Whether that's a simple return of a favor or a sign of a larger amount of support from Team Blunt remains to be seen. The jury is still out on Steelman as a candidate, especially after she severely wounded the GOP's governor candidate in their 2008 primary. If Blunt jumps on board with Steelman, though, that would discourage other Republicans like Graves and Wagner (who was chairman of Blunt's campaign) and could help Steelman avoid another bruising primary.
