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.

* In West Virginia’s closely-watched U.S. Senate race, a new survey from Public Policy Polling shows Gov. Joe Manchin (D) back out in front of John Raese (R), 48% to 45%.

* A Nevada woman has come forward to say she worked for gubernatorial hopeful Brian Sandoval (R), despite being an illegal immigrant at the time. This is particularly relevant, given that Sandoval is running on an anti-immigrant platform.

* In Florida’s gubernatorial race, a new Quinnipiac poll shows disgraced former health care executive Rick Scott (R) with the narrowest of leads over state CFO Alex Sink (D), 45% to 44%.

* Speaking of Florida, President Obama has cut a radio ad for Rep. Kendrick Meek’s (D) U.S. Senate campaign, calling Meek “a powerful voice for Floridians.”

* Arizona Gov. Jan Brewer (R) appears undamaged by her humiliating debate performance. A new Rocky Mountain poll shows her leading state Attorney General Terry Goddard (D), 46% to 35%, among likely voters.

* In Colorado’s gubernatorial race, Republican Dan Maes, currently running third in the poll, is blaming his supporters for his current electoral difficulties.

* As Democratic triage efforts begin in earnest, the national party is pulling back in its investments in support of Reps. Steve Driehaus of Ohio, Suzanne Kosmas of Florida, Kathy Dahlkemper of Pennsylvania, and Stephanie Herseth Sandlin of South Dakota.

* After revelations about his habit of dressing up like a Nazi for several years, Republican congressional candidate Rich Iott in Ohio was quietly thrown under the GOP bus. Yesterday, Iott made clear he’s not happy about it.

* In the state of Washington, Dems appear to have a rare pick-up opportunity in the 8th congressional district. A new PPP poll commissioned by Daily Kos shows incumbent Rep. Dave Reichert (R) leading by just three over his Democratic challenger, Suzan DelBene, 49% to 46%.
