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.

* More than half a year after the election, the Minnesota Supreme Court will begin considering Norm Coleman’s case today.

* Sen. Tom Coburn (R-Okla.) ended the suspense this morning and announced that he will seek re-election next year. Though there were several Democrats eyeing the race if Coburn retired, the incumbent will enter the race as the strong favorite.

* In Florida, state Sen. Dan Gelber (D) appears to be ending his Senate campaign, telling supporters he’s “taking a step back” from the race. Gelber’s departure leaves Rep. Kendrick Meek (D) as the likely Democratic nominee.

* The DCCC will begin airing radio ads today, targeting six vulnerable House Republicans for having voted against President Obama’s economic stimulus package.

* If his comments on MSNBC late last week were any indication, Pennsylvania Gov. Ed Rendell (D) will be pretty aggressive in supporting Sen. Arlen Specter over Rep. Joe Sestak in a Democratic Senate primary next year.

* Voters in New Jersey will head to the polls tomorrow to choose the major parties’ gubernatorial candidates. Gov. Jon Corzine is facing token opposition in a Democratic primary, but the Republican primary contest between former U.S. Attorney Chris Christie and former Bogota mayor Steve Lonegan has proven harder to predict.
