TUESDAY’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 bad news for Senate Majority Leader Harry Reid (D-Nev.) is that a new Mason-Dixon poll, conducted for the Las Vegas Review-Journal, shows the senator with weak support the year before his re-election bid. The good news for Reid is that Republicans still can’t find a credible challenger.

* In light of Brian Moran’s latest push, Terry McAuliffe’s gubernatorial campaign in Virginia has a new video with evidence that he really did support President Obama’s general-election campaign last year.

* Even before the state Supreme Court’s consideration of the case, a majority of Minnesotans want to see former Sen. Norm Coleman (R) concede to Al Franken immediately. The same Rasmussen poll showed a 67% majority wants to see Gov. Tim Pawlenty (R) sign Franken’s election certificate if Coleman loses at the state Supreme Court.

* Merrick Alpert, a former aide to Al Gore and an Air Force officer in Bosnia, announced yesterday that he’ll challenge Sen. Chris Dodd in a Democratic primary in Connecticut next year.

* Let’s just summarize the latest Rasmussen poll in New York quickly: Gov. David Patterson (D) would easily lose to his likely Republican challengers, while state Attorney General Andrew Cuomo (D) would easily win those same match-ups.

* Sen. Lindsey Graham (R-S.C.) ran into some Ron Paul fans at the state Republican convention the other day, who didn’t like it when Graham said, “Ron Paul is not the leader of this party…. I’m not going to give this party over to people who can’t win.”

* And Republicans may not agree with Bruce Springsteen’s liberal politics, but that doesn’t mean they mind exploiting his popularity for GOP fundraising efforts.
