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.

* No matter which poll you rely on, New Jersey’s gubernatorial race is close. While a Fairleigh Dickinson poll showed Gov. Jon Corzine (D) lead Chris Christie (R) by one point yesterday, the latest Rasmussen poll shows Christie up by three, 47% to 44%. Two weeks ago, Rasmussen put Christie’s lead at seven points.

* On a related note, Vice President Biden will be in New Jersey later today, and will appear at an event for Corzine.

* In Virginia, Democratic gubernatorial hopeful Creigh Deeds said yesterday that “what’s going on in Washington” has made his own campaign “very tough.” It’s not a good sign when, a month before the election, the candidate starts blaming others.

* Republicans’ chances of winning Iowa’s 2010 gubernatorial race got a little better today, when former Gov. Terry Branstad (R) filed the paperwork for his comeback bid. Early polls show him looking extremely strong against incumbent Gov. Chet Culver (D).

* The Democratic Senate primary in Florida gets a little more crowded today when former Miami Mayor Maurice Ferre enters the race. Ferre, who is 74, last sought public office in 2001, when he lost a re-election campaign in Miami.

* In a Democratic pollster, but the latest survey from Momentum Analysis shows Robin Carnahan (D) leading Roy Blunt (R) in Missouri’s 2010 Senate race, 48% to 45%.

* In Kansas, a Survey USA poll shows Jerry Moran leading Todd Tiahrt in the Republican Senate primary, 43% to 27%. About a third of Kansas Republicans are still undecided.

* And in Vermont, Sen. Pat Leahy (D) is considered a lock for re-election, but he’ll apparently face a primary challenge from the left.
