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.

* Sen. Arlen Specter of Pennsylvania has pretty much ruled out seeking re-election as a Democrat. But how about running as an independent? It remains a distinct possibility.

* Republican Assemblyman Jim Tedisco, running in the special election in New York’s 20th, has a new ad downplaying his party identification, and apparently hoping to connect himself to President Obama.

* It’s not clear which Democratic candidate will emerge in Ohio’s open Senate race, but Ohio voters nevertheless seem to prefer Sen. George Voinovich’s (R) seat get filled by a Democrat. New polling data shows both Secretary of State Jennifer Brunner (D) and Lt. Gov. Lee Fisher (D) leading Republicans Rob Portman and Mary Taylor.

* Speaking of Ohio, Gov. Ted Strickland (D) remains popular, but the state’s struggling economy has taken its toll on the governor’s approval ratings. Strickland faces reelection in 2010.

* Jeffrey Frederick, the embattled chairman of the Virginia Republican Party, is still struggling to hold onto his job, but he’s refusing to resign.

* Rep. Ellen Tauscher (D-Calif.) is headed to Obama’s State Department, meaning there will be another special election fairly soon. There’s already a race underway to replace Labor Secretary Hilda Solis in her former Los Angeles-area district.

* It seems terribly silly to even think about 2012 presidential polling, but in the interest of comprehensive coverage, I suppose I should mention that Public Policy Polling asked respondents to consider a hypothetical match-up featuring Barack Obama and Sarah Palin. The president leads by 20 points, 55% to 35%.
