THURSDAY’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.

* Sen. David Vitter (R) may be plagued by multiple scandals, but as the incumbent, it’s largely assumed he’ll enjoy the support of the party establishment, both in D.C. and Louisiana. But as of this week, Louisiana Gov. Bobby Jindal (R) has declined to endorse Vitter in his primary campaign.

* Democrats in Rhode Island hope to win back the governor’s mansion this year, and those odds probably improved a bit yesterday when the party managed to avoid a primary. State Attorney General Patrick Lynch signaled his intention to end his campaign, clearing the way for state Treasurer Frank Caprio.

* The sketchy infomercial probably didn’t help J.D. Hayworth’s Republican Senate bid in Arizona. A new Rocky Mountain poll shows incumbent Sen. John McCain (R) crushing his primary challenger, 64% to 19%.

* It’s a Democratic poll, not an independent one, but the latest numbers out of Nevada show Senate Majority Leader Harry Reid (D) leading Sharron Angle (R), 44% to 40%.

* On a related note, Angle is no longer threatening to sue Reid for re-publishing her old website online. In all seriousness, the Reid campaign has to be disappointed, because the lawsuit would have been campaign gold.

* In Connecticut, a new Quinnipiac poll shows Ned Lamont leading Dan Malloy in a Democratic gubernatorial primary, 46% to 37%. Either Dem leads Tom Foley (R) by double digits in the general election.

* Speaking of Connecticut, is former Rep. Rob Simmons (R), who suspended his Senate campaign six weeks ago, seriously thinking about getting back into the race? It sure sounds like it.

* In North Carolina, the latest SurveyUSA poll shows incumbent Sen. Richard Burr (R) leading Elaine Marshall (D), 46% to 36%.

* And in Georgia’s Republican gubernatorial primary, former Rep. Nathan Deal is slamming former secretary of state Karen Handel for not hating gay people.
