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.

* Looks like Rep. Michael Capuano (D-Mass.) is joining the Democratic field in Massachusetts’ special election to fill Ted Kennedy’s Senate vacancy. Former Rep. Marty Meehan (D-Mass.) formally announced yesterday that he will not run.

* The primaries in Massachusetts won’t be held for another three months, and the field isn’t close to being complete. At this point, though, state Attorney General Martha Coakley leads a multi-candidate Democratic field according to a new Rasmussen poll.

* Former Colorado Lt. Gov. Jane Norton (R) will, after NRSC recruiting efforts, run for the Senate next year. She filed the paperwork yesterday and will formally launch a campaign next week. Norton will face a GOP primary, but is widely considered to be the favorite.

* There’s a crowded Republican field in Connecticut, where several GOP candidates hope to take on incumbent Sen. Chris Dodd (D) next year, but former Rep. Rob Simmons (R) seems to be the choice of the Republican in-state establishment.

* Rep. Anh “Joseph” Cao (R-La.) is widely considered the most vulnerable House Republican incumbent next year, and he now has his first official Democratic challenger: state Rep. Cedric Richmond. Expect a crowded primary.

* And in Nebraska, Rep. Lee Terry (R) is considered a possible Democratic target next year, and the DCCC has apparently convinced state Sen. Tom White (D) to take on the incumbent.
