TUESDAY’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:

* As expected, Joe Miller (R), after a series of legal and electoral setbacks, is taking his case to the state Supreme Court. Miller still hopes to disqualify about 8,000 ballots that were cast for Sen. Lisa Murkowski (R).

* Remember the secretive right-wing campaign outfit, Crossroads GPS? The Rove-backed attack operation is already taking steps to go after vulnerable House Dems, launching a $400,000 radio ad campaign this week, targeting 12 Democrats who narrowly won re-election last month.

* Former wrestling executive Linda McMahon (R) lost badly in her U.S. Senate campaign in Connecticut last month, but she’s apparently not done trying. Perhaps eyeing the 2012 cycle, McMahon has scheduled a D.C. meeting with National Republican Senatorial Committee Chairman John Cornyn.

* Recent polling suggests former Gov. John Engler is the strongest Republican candidate to take on Sen. Debbie Stabenow in 2012, but Engler said yesterday he’s not interested in the race.

* In Virginia, a Clarus Research Group poll shows incumbent Sen. Jim Webb (D) with the narrowest of leads over former Sen. George Allen (R) in a hypothetical 2012 match-up. The poll showed Webb up by one point, 41% to 40%.

* Former White House Chief of Staff Rahm Emanuel (D) is talking to the Chicago Board of Elections this morning, hoping to establish residency and clear the way for his mayoral campaign.

* Outgoing Rep. Artur Davis (D-Ala.) was, up until quite recently, considered a rising star in Democratic politics. But after a surprisingly awful showing in Alabama’s Democratic gubernatorial primary earlier this year, Davis lashed out at his party, and now wants to see an independent party in his Southern state.
