WEDNESDAY’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 Florida’s Republican Senate primary, Gov. Charlie Crist was, just a few months ago, considered the prohibitive favorite. A new Rasmussen poll now shows him tied with former state House Speaker Marco Rubio, with each garnering 43% support.

* After four House Dems announced their retirements over four weeks, GOP leaders are starting rumors about other possible departures. It prompted several prominent Democratic incumbents to announce yesterday that they will run for re-election next year, despite rumors to the contrary.

* The Democratic Congressional Campaign Committee has put together a new video, going after five Republican lawmakers — Dan Lungren and Mary Bono Mack of California, Lee Terry of Nebraska, Joe Wilson of South Carolina, and Charlie Dent of Pennsylvania — for voting against reforming Wall Street.

* In Florida’s open gubernatorial race, state Attorney General Bill McCollum (R) leads state CFO Alex Sink (D) in a new Rasmussen poll, 44% to 39%. McCollum’s five point lead was 11 points in a Rasmussen poll a couple of months ago.

* Former Rep. J.D. Hayworth (R) has reportedly been thinking about taking on Sen. John McCain (R) in a primary in Arizona next year, but he may not be quite as competitive as he thought — a new poll shows McCain leading in a hypothetical match up by 20 points.

* Rep. Mark Kirk (R-Ill.) continues to move quickly away from his moderate record in advance of his Senate campaign. Just two months ago, Kirk supported transferring detainees out of Gitmo. Yesterday, he reversed course.

* In Colorado, former Lt. Gov. Jane Norton (R), hoping to pick up right-wing support for her Senate campaign, has announced her support for eliminating the U.S. Department of Education.

* Sen. Joe Lieberman (I-Conn.) apparently intends to seek another term in 2012, and he hasn’t ruled out running as a Republican.
