THURSDAY’S CAMPAIGN ROUND-UP…. Today’s installment of campaign-related news items that wouldn’t necessarily generate a post of their own, but may be of interest to political observers:

* Democratic Congressional Campaign Committee Chairman Steve Israel (D-N.Y.) has assembled an alumni association of sorts — he holds regular conference calls with nearly all of the Dems who lost their seats in 2010. Israel apparently hopes to set up a series of rematches, starting with the 14 districts Kerry won in 2004, Obama won in 2008, but which Republicans won in 2010.

* While DNC Chairman and former Gov. Tim Kaine decides whether to launch a Senate campaign in Virginia, former Rep. Tom Perriello (D-Va.) said he won’t run if Kaine does. If Kaine passes, Perriello added, “I will consider it.”

* In Pennsylvania, a new Quinnipiac poll shows Sen. Bob Casey Jr. (D) with a reasonably good 44% to 24% approval rating. A 46% plurality believes Casey, who’ll seek re-election next year, deserves another term.

* On a related note, the same Quinnipiac poll shows Pennsylvania voters preferring President Obama to a generic Republican challenger, 45% to 39%.

* Recent rumors have suggested that Sen. John Thune (R-S.D.) would skip the 2012 presidential race, but “he is suddenly very eager to get his name out there.” This includes interviews this week with National Review and radical TV preacher Pat Robertson’s Christian Broadcasting Network.

* Rep. Michele Bachmann (R-Minn.), for whatever reason, appears to be moving forward with plans for a presidential campaign, including a trip to New Hampshire on March 11 and 12.

* As former Sen. Rick Santorum (R-Pa.) inches closer to his own presidential campaign, he realizes he has a Google problem. Thanks to Dan Savage, searching for Santorum’s name produces results of an adult nature.

* And if Indiana Gov. Mitch Daniels (R) launches a presidential campaign, he can expect very little support from Rush Limbaugh. Daniels told CPAC’s audience last week that the Republican Party “will need people who never tune in to Rush or Glenn or Laura or Sean, who surf past C-SPAN to get to SportsCenter.” This did not go over well with the right-wing radio host.
