MONDAY’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.

* The Club for Growth’s political action committee formally endorsed Marco Rubio’s (R) Senate campaign in Florida this morning, reinforcing expectations of a bitter fight in the Sunshine State over whether Gov. Charlie Crist (R) is right-wing enough for the party base.

* While most of the Republican establishment is excited about former state Attorney General Kelly Ayotte’s (R) Senate campaign in New Hampshire, Ovide Lamontagne (R) is launching a campaign of his own. Lamontagne was the GOP’s gubernatorial nominee in 1996, when he lost to Jeanne Shaheen (D), and hasn’t sought elective office since.

* In Illinois, Rep. Mark Kirk (R) wants Sarah Palin’s endorsement for his Senate campaign, but is he seeking Glenn Beck’s support, too? Kirk apparently doesn’t want to talk about it.

* Roxanne Conlin, who ran for governor in Iowa unsuccessfully 27 years ago, has decided to take on Sen. Charles Grassley (R-Iowa) next year.

* A new poll (pdf) conducted for the Los Angeles Times and the University of Southern California suggests Golden State Democrats are not yet entirely sold on Jerry Brown’s (D) gubernatorial campaign. Most want another choice, offering a possible opening to Sen. Dianne Feinstein (D), who conceded last week that she hadn’t ruled out the possibility of running for governor next year.

* Speaking of California, most state Republicans don’t yet know much about the GOP Senate candidates, but at this point, Carly Fiorina and Chuck DeVore — the Republicans hoping to get the party nod to take on Sen. Barbara Boxer (D) — are tied at 27% each.

* And in Iowa over the weekend, Minnesota Gov. Tim Pawlenty (R) continued his unannounced presidential campaign at the state Republican Party’s annual event at the state fairgrounds. Reviews were mixed.
