WEDNESDAY’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.

* Will RNC Chairman Michael Steele be subjected to a no-confidence vote next month? There’s a real possibility, and Katon Dawson, chairman of the South Carolina GOP, appears to be the ring-leader.

* Arlen Specter may catch a big break with far-right activist Peg Luksik moving towards a Republican primary challenge. If both Luksik and Pat Toomey split the right-wing vote next year, Specter’s chances of winning the primary improve.

* On a related note, Toomey, the former Republican congressman who nearly defeated Specter in 2004, has indicated he’s likely to run, but the official announcement is due “very soon.”

* Al Franken’s lawyers will rest their case today in Minnesota.

* President Obama, still popular: “The 61 percent approval rating is also slightly higher than his predecessors’ numbers around the same time. George W. Bush stood at 58 percent around 50 days into his administration, with Bill Clinton at 53 percent, George H.W. Bush at 56 percent and Ronald Reagan at 60 percent.”

* If Delaware Attorney General Beau Biden (D) runs for his father’s former Senate seat, he may have a real tough race on his hands. The latest PPP survey shows Biden trailing Rep. Mike Castle (R) in a hypothetical match-up, 44% to 36%.

* In a bit of a surprise, Rep. Henry Brown (R-S.C.) will face a primary challenge next year. Brown’s narrow win last November might have something to do with this.
