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.

* Marco Rubio’s (R) Senate campaign in Florida got a little help today, with endorsements from Mike Huckabee and Jeb Bush, Jr. (the former governor’s son).

* Liz Cheney, who was on national television again yesterday (natch), said she’s not focused on seeking elected office “right now.”

* New York Gov. David Paterson’s (D) re-elections chances remain pretty awful. A new Siena College poll put his favorability rating statewide at 27%.

* Rep. Jack Murtha (D-Pa.), now in his 19th term, will face a primary challenge for the first time. Former naval officer Ryan Bucchianeri, a graduate of Harvard’s Kennedy School of Government, announced yesterday he will take on the incumbent.

* Florida may be one of the nation’s most diverse states, but the Republican Party will run a slate of middle-aged white men in all of the major statewide races next year.

* According to a new Quinnipiac poll, Sen. Chris Dodd (D-Conn.) is still struggling in his re-election chances next year, but he seems to have turned a corner. He now trails former Rep. Rob Simmons by six (45% to 39%), after trailing by 16 points in April.

* Speaking of Dodd, Peter Schiff, a libertarian brokerage firm owner who predicted the U.S. financial meltdown, is “leaning towards” a Senate campaign in Connecticut next year.

* Rep. Anthony Weiner (D-N.Y.) announced this morning that he is not running for mayor in NYC. City Comptroller William Thompson is now the likely Democratic nominee.

* Retired professional football player Mike Minter (R) had been slated to run against Larry Kissell (D) in North Carolina next year, but yesterday, Minter took a pass on the race.
