Another familiar face is jumping in the race to replace Rep. Mary Fallin (R-Okla.). Physician Johnny Roy, who took 3 percent in the 2006 primary, joins state Rep. Mike Thompson and former state Rep. Kevin Calvey, another repeat candidate. But all eyes will be on Oklahoma City Mayor Mick Cornett, who took Fallin to a primary runoff in 2006.

Just hours after his office indicated he was looking seriously at the upcoming Senate appointment, Rep. Lincoln Diaz-Balart (R-Fla.) said he will not seek Sen. Mel Martinez's (R-Fla.) seat, after all. Now attention turns to whoever else Gov. Charlie Crist (R) asks to submit questionnaires for the appointment.

A Florida Chamber of Commerce poll shows state Attorney General Bill McCollum (R) leading state Chief Financial Officer (CFO) Alex Sink 43-34 in the race to replace Crist. Crist's approval is at 67 percent, while his disapproval is at 27 percent. There are no head-to-head numbers in the Senate race, for some reason.

Former Colorado Lt. Gov. Jane Norton (R) emerges as a potential addition to the field looking to face appointed Sen. Michael BennetMichael Farrand BennetColorado senators pitch immigration compromise Colorado senators mark Olympics with Senate hallway curling GOP Senate candidate fundraising lags behind Dems in key races MORE (D-Colo.). With no big names yet in the race and former Rep. Bob Beauprez (R) unsure of whether he'll jump in, Norton could wind up being the frontrunner.

In related news, Public Policy Polling just released a survey showing Bennet has a 31-38 approval-disapproval, and Beauprez and the two declared candidates - Aurora City Councilman Ryan Frazier and Weld County District Attorney Ken Buck - also have negative approvals. Bennet trails Beauprez 42-39 but leads Buck 39-35 and Frazier 38-33.

Connecticut state Sen. Dan Debicella (R) will take the reins from his state Senate colleague, John McKinney, and run against freshman Rep. Jim Himes (D-Conn.). But with McKinney declining to run, Republicans now face a primary, with former state Sen. Bob Russo also declaring his candidacy. Not great news with an August primary and an expensive media market, but at least Republicans will have a reputable nominee.

The latest word from Sen. Kay Bailey Hutchison (R-Texas) on when she'll resign from the Senate seems to be sometime after Sept. 30. "I haven't set a timetable because there are certain things that I need to do," she said Monday. "The end of the fiscal year is Sept. 30 and I've got huge responsibilities for Texas that I have to fulfill by Oct. 1." Resigning after late September, of course, would also push the special election to May of next year, versus November of this year. And Republicans would prefer that.
