THURSDAY’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.

* Another poll, another piece of evidence that New Jersey’s gubernatorial race is tightening. This morning, a Monmouth University/Gannett New Jersey Poll shows Chris Christie’s (R) lead over incumbent Gov. Jon Corzine (D) down to three, 43% to 40%. Independent Chris Daggett is third with 8%.

* While most recent polling in Virginia shows a very tight race, a new Rasmussen poll shows Bob McDonnell (R) expanding on his earlier lead over Creigh Deeds. Rasmussen now has McDonnell up by nine, 51% to 42%.

* A new Quinnipiac poll out of Pennsylvania shows Sen. Arlen Specter leading Rep. Joe Sestak in a Democratic primary, 44% to 25%. While the 19-point margin may sound discouraging for Sestak fans, it’s worth noting that Quinnipiac showed Specter leading by 32 points in July. At this point, former Rep. Pat Toomey (R) has narrow leads over both Dems in hypothetical match-ups.

* Former Nevada state Republican Party Chairwoman Sue Lowden officially kicked off her Senate campaign against Senate Majority Leader Harry Reid (D) today. She’ll join a crowded GOP primary field, though Lowden seems to enjoy some early support from the party establishment.

* Former eBay CEO Meg Whitman (R), running for governor in California, is still trying to explain why she didn’t even register to vote until she was 46. Whitman said yesterday she was busy with her family, though she added, “It is no excuse. My voting record, my registration record, is unacceptable.”

* In the three-way, special election contest in New York’s 23rd, a new Siena poll shows Dede Scozzafava (R) out in front with 35%, followed by Bill Owens (D) with 28%, and Conservative Party candidate Doug Hoffman with 16%.

* And in Louisiana, Gov. Bobby Jindal (R) was asked about his willingness to support scandal-plagued Sen. David Vitter’s (R) re-election campaign. “We haven’t made that decision yet,” Jindal said.
