TUESDAY’S CAMPAIGN ROUND-UP…. Today’s installment of campaign-related news items that wouldn’t generate a post of their own, but may be of interest to political observers.

* Former Rep. Nathan Deal (R) resigned from Congress last week, ostensibly so he can focus on his gubernatorial campaign. As he departs, the House Ethics Committee wrapped up its report on allegations surrounding Deal, and concluded yesterday that he appeared to have acted improperly.

* Chuck DeVore (R), running for the Senate in California, has “severed all ties” with Erik Brown. Brown is the consultant best known for getting reimbursed for “meals” at a Los Angeles bondage nightclub.

* In Missouri, the latest survey from Public Policy Polling shows Rep. Roy Blunt (R) edging ahead of Missouri Secretary of State Robin Carnahan (D) in this year’s open Senate race, 45% to 41%.

* In Ohio’s Democratic Senate primary, Quinnipiac shows Lt. Gov. Lee Fisher leading Ohio Secretary of State Jennifer Brunner, 33% to 26%. A plurality of Democratic voters remains undecided.

* The latest Research 2000 poll in Wisconsin shows incumbent Sen. Russ Feingold (D) with comfortable leads over his announced GOP challengers. If former Gov. Tommy Thompson (R) runs, Feingold’s lead is just four points, 48% to 44%.

* Republicans are struggling to find a credible opponent for Sen. Kirsten Gillibrand (D) in New York, but a new Marist poll shows former Gov. George Pataki (R) leading the appointed incumbent by two in a hypothetical match-up.

* In Arkansas’ Democratic Senate primary, Lt. Gov. Bill Halter’s new commercial goes after Sen. Blanche Lincoln for having supported TARP in 2008.

* And putting rumors to an end, House Budget Committee Chairman John Spratt (D-S.C.) officially filed for re-election yesterday.
