Today’s installment of campaign-related news items that won’t necessarily generate a post of their own, but may be of interest to political observers:

* In a fairly impressive display, President Obama’s re-election campaign raised $42 million in the last quarter, and an additional $24 million for the Democratic National Committee. The combined $66 million can be used for the presidential campaign.

* Speaking of fundraising, in Massachusetts’ closely-watched U.S. Senate race, Sen. Scott Brown (R) raised $3.2 million in the last three months of 2011, which appeared to be pretty good. A day later, however, we learned that Democrat Elizabeth Warren raised $5.7 million over that same time period.

* Investment fund executive and top GOP donor Barry Wynn was backing Rick Perry’s presidential campaign, but in light of the Texas governor’s criticism of Bain Capital, Wynn is withdrawing his support.

* Speaking of Perry, CNN appears to have gone out of its way to ensure he’s eligible to participate in its upcoming debate.

* Former Ambassador John Bolton, perhaps best known for never seeing a war he didn’t want to start, endorsed the Romney campaign this morning. Bolton, also a Fox News analyst, considered launching a presidential campaign of his own last year.

* In Florida’s closely-watched U.S. Senate race, Quinnipiac shows incumbent Sen. Bill Nelson (D) leading Rep. Connie Mack III (R) by the narrowest of margins, 41% to 40%.

* In Ohio, Rick Santorum’s name won’t appear on the ballot at the district level in three congressional districts. The state’s primary isn’t until March 6, at which point the race will probably be over anyway.

* And in Nebraska, Karl Rove’s attack operation, American Crossroads, is already launching attack ads against Bob Kerrey — and Kerrey hasn’t even announced whether he’s running yet. Crossroads will reportedly spend $30,000 on the commercials, which run through the weekend.
