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.

* Following a week of criticism, Connecticut Attorney General and Senate hopeful Richard Blumenthal (D) apologized for having used misleading rhetoric about his military service. He told the Hartford Courant, “I have made mistakes and I am sorry. I truly regret offending anyone.”

* As expected, New York Attorney General Andrew Cuomo (D) launched his gubernatorial campaign on Saturday. A new Siena poll already shows him with enormous leads over his GOP challengers.

* A St. Petersburg Times/Miami Herald/Bay News 9 poll released over the weekend shows Gov. Charlie Crist’s (I) departure from the Republican Party continuing to help his Senate prospects. Crist currently leads in the three-way match-up with 30% support, followed by Marco Rubio (R) at 27%. Rep. Kendrick Meek (D) is running third with 15%. (thanks to reader V.S. for the tip)

* Former wrestling executive Linda McMahon (R) won her state party’s endorsement in the Connecticut Senate race. Former Rep. Rob Simmons (R), the one-time favorite, had said he would drop out of the race if he didn’t receive the state GOP’s nod at the convention. He’s since changed his mind, and will take on McMahon in a primary.

* Colorado’s major parties held their party conventions over the weekend. On the Republican side, Weld County Prosecutor Ken Buck came out on top, though former Lt. Gov. Jane Norton skipped the convention and plans to petition her way onto the primary ballot. Among Dems, former state House Speaker Andrew Romanoff defeated appointed Sen. Michael Bennet.

* Karl Rove began offering Rand Paul’s Senate campaign in Kentucky some strategic/media advice last week.

* In a surprise move, Dick Leinenkugel ended his Republican Senate campaign in Wisconsin yesterday, just a month after getting started. Leinenkugel threw his support to businessman Ron Johnson, who kicked off his campaign after being inspired by a Dick Morris appearance on Fox News.

* The latest Research 2000 poll in California shows former Rep. Tom Campbell leading Carly Fiorina in the GOP Senate primary, 37% to 22%. The same poll shows Meg Whitman still leading the GOP gubernatorial primary over Steve Poizner, but the margin has shrunk from 33 points to 10.
