FRIDAY’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.

* Florida Gov. Charlie Crist (R) has chosen his former chief of staff, George LeMieux, to replace Sen. Mel Martinez (R) through the end of next year. LeMieux is Crist’s closest political advisor and serves as deputy state attorney general until 2006.

* To the widespread disappointment of Democrats everywhere, Mitt Romney will not run for Ted Kennedy’s Senate seat in January.

* A Democracy Corps poll in New Jersey shows Chris Christie (R) leading incumbent Gov. Jon Corzine by just two points, 43% to 41%, with independent Chris Daggett with 7% support. In a head-to-head contest, Christie is up by three, 46% to 43%.

* Rex Rammell, a Republican gubernatorial candidate in Idaho, joked this week about hunting President Obama. He later said he was kidding, and “would never support him being assassinated.”

* As if Sen. David Vitter’s (R-La.) re-election prospects weren’t challenging enough — he’s facing a credible Democratic challenger and is burdened by a prostitution scandal — he may soon face a primary challenge from Gen. Russell Honore.

* Vermont Gov. Jim Douglas (R) will step down next year after four terms, but he will not run for president in 2012.

* On a related note, as much as I appreciate the kind emails, I will not be running to replace Douglas as governor next year.

* Theocrat Roy Moore (R), running for governor in Alabama next year, has secured an endorsement from actor Chuck Norris.
