WEDNESDAY’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:

* Any hopes Minnesota gubernatorial nominee Tom Emmer (R) had of closing the gap against Mark Dayton (D) were shot down yesterday by the state Supreme Court.

* On a related note, Emmer is expected to concede any minute now.

* Speaking of resolving lingering elections, Rep. Tim Bishop (D) has officially won re-election in New York’s 1st congressional district, with Randy Altschuler (R) finally conceding. It was the last unresolved U.S. House race, and puts the final number of net Republican gains at 63.

* In the very last unresolved race of 2010, Alaska’s U.S. Senate race, a state court will hear arguments today in Joe Miller’s (R) lawsuit. The AP noted, “A decision in Miller’s favor could result in thousands of challenged ballots for incumbent Sen. Lisa Murkowski being tossed and lead to a recount.”

* Sen. Joe Lieberman (I) will likely face a tough challenge, but it won’t come from Ned Lamont (D), who said yesterday’s he’s strongly disinclined to run again. The most likely Democratic candidates, at this point, are Rep. Christopher Murphy and Connecticut Secretary of the State Susan Bysiewicz.

* Failed U.S. Senate candidate Christine O’Donnell (R) is in the process of forming a political action committee. She’s not, in other words, going away.

* In Minnesota, Sen. Amy Klobuchar (D) is up for re-election in 2012, and a new survey from Public Policy Polling shows her “overwhelmingly popular” in her home state. In hypothetical match-ups, she has sizable leads among all potential GOP challengers, including a double-digit lead over Gov. Tim Pawlenty (R), though he’s far more likely to run for president.
