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.

* Former Rep. Charles Bass (R-N.H.), swept out of office four years ago in the midst of Republican failures, is now running to get his old job back. It’s an open seat race in New Hampshire’s 2nd district, with Rep. Paul Hodes (D-N.H.) running for Senate.

* Auto dealer and right-wing activist Tom Ganley (R) is ending his Senate primary campaign in Ohio — he’s been running an up-hill fight against Rob Portman, Bush’s former budget director — and will instead run against Rep. Betty Sutton (D).

* President Obama will be in Colorado today, to help generate support for Sen. Michael Bennet (D), who was appointed to the Senate last year, and is seeking a full term this year.

* Rep. Brad Ellsworth (D) is apparently very interested in running for the Senate in Indiana this year, but the DCCC hates to lose an incumbent in a district Republicans would likely pick up.

* Most of the potential Democratic candidates in Indiana are not well known statewide, and in a new Rasmussen poll, trail corporate lobbyist Dan Coats (R) in hypothetical general-election match-ups.

* In Kansas, there were real concerns that Sen. Sam Brownback (R) would run for governor effectively unopposed. Yesterday, however, state Sen. Tom Holland (D) announced he would take on the heavy favorite.

* In Vermont’s gubernatorial race, Secretary of State Deb Markowtiz (D) has a narrow lead over Lt. Gov. Brian Dubie (R), 43% to 41%. Markowitz is part of a crowded Democratic primary field, but the other Dems trail Dubie in hypothetical match-ups.

* And in 2012 news, former Sen. Rick Santorum (R-Pa.) seems pretty serious about running for president (yes, of the United States).
