MONDAY’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.

* Rep. Joe Sestak (D-Penn.) hasn’t officially launched his Senate campaign, but he is in the midst of a statewide tour. His remarks to voters don’t leave any doubt: “This isn’t something I wanted to do four months ago, but it has to be done. Someone has to be in this race that’s credible.”

* In an impressive display, Florida Gov. Charlie Crist (R) appears to have raised nearly $3 million in his first fundraising quarter as a Senate candidate. It’s a reminder of just how much establishment support Crist enjoys, and the extent to which Republicans are desperate to keep this seat.

* With Alaska Lt. Gov. Sean Parnell (R) moving up to the governor’s office later this month, Rep. Don Young (R) is glad to know Parnell won’t be challenging him in another Republican primary next year.

* New Hampshire Attorney General Kelly Ayotte (R) is mulling a Senate campaign, but Gov. John Lynch (D) is reminding her that, not too long ago, she committed to serving a full term, which runs through 2013.

* Rep. Lee Terry (R) of Nebraska is considered a possibly vulnerable incumbent, and now appears to have a credible challenger. State Sen. Tom White (D) has launched an exploratory committee, to the delight of the DCCC.

* Dan Glickman was a Democratic House member, the Secretary of Agriculture, and is now chairman of the Motion Picture Association of America. Is his next move a Senate campaign in Kansas? He’s thinking about it, but doesn’t sound anxious to throw his hat into the ring.
