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.

* A new national AP poll shows Democrats leading Republicans by six, 44% to 38%, on the generic congressional ballot.

* Scandal-plagued right-wing activist Ralph Reed (R) considered running for Congress in Georgia this year, but announced this morning he will remain in the private sector.

* In Nevada, Jon Scott Ashjian is running for the Senate as a Tea Party candidate, and it’s not entirely surprising that Republicans are attacking him as a phony. Both of the leading GOP candidates are accusing Ashjian of being a Democratic plant, intended to split the right.

* In Michigan, Connie Saltonstall, a former teacher and county commissioner, announced yesterday she will take on Rep. Bart Stupak in a Democratic primary. The election will be in early August. (thanks to reader K.B.)

* Speaking of primaries, Rep. Mike Castle (R) was expected to cruise to his party’s Senate nomination in Delaware this year, but conservative activist Christine O’Donnell is poised to take him on in a GOP primary. O’Donnell was the Republican nominee against Joe Biden in 2008. Castle remains the odds-on favorite.

* Florida Senate candidate Marco Rubio is launching his first television ad today. It will run on Fox News stations across the state.

* And in Arkansas, Republicans had high hopes of picking up Rep. Marion Berry’s (D) seat after the incumbent announced his retirement, but with the filing deadline having come and gone, and with no credible GOP candidates getting into the race, independent observers now believe Dems will likely keep the seat.
