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.

* Gov. Jon Corzine’s (D) campaign released a very aggressive new ad yesterday, going after Chris Christie (R) for throwing “his weight around” as a U.S. attorney to gain special treatment.

* Will Northern Virginia dictate another statewide race? With just six weeks left in Virginia’s gubernatorial campaign, Mark Blumenthal takes a closer look.

* Republicans’ scorched-earth efforts throughout August helped generate a wildly successful fundraising month for the RNC.

* New York Gov. David Paterson (D) conceded that he would not seek another term if he thinks his candidacy would hurt his party.

* In Arizona, the latest survey from Public Policy Polling shows state Attorney General Terry Goddard with comfortable leads in next year’s gubernatorial race over all of her his likely GOP challengers, including incumbent Gov. Jan Brewer. Brewer, who took office after Janet Napolitano (D) joined the Obama cabinet, has an approval rating of just 26%.

* In Iowa, a new Rasmussen poll shows former Gov. Terry Branstad (R) looking very strong, if he decides to seek his old job. In a hypothetical match-up, Branstad leads incumbent Gov. Chet Culver (D) by 20 points, 54% to 34%.

* Speaking of Iowa, Rasmussen also shows Sen. Charles Grassley (R) with a huge lead over his likely Democratic challenger Bob Krause, 56% to 30%. Krause, who served in the state and had a 20-year career with the state’s Department of Transportation, is not widely known.

* And the Ron Paul fundraising machine continues to be effective, as evidenced by Rand Paul’s $1 million in contributions. Rand, the Texas Republican’s son, is an ophthalmologist running for the U.S. Senate in Kentucky.
