Friday’s campaign round-up

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:

* As of this morning, it’s official: Florida is moving its presidential primary to Jan. 31, ignoring the pleas of the Republican National Committee. South Carolina has already vowed to move its primary up in response, which will cause Nevada to move up its caucuses, which will cause New Hampshire to move up its primary, which will cause Iowa to move up its caucuses.

* Rick Perry’s campaign has a new video going after Mitt Romney for flip-flopping on economic stimulus.

* On a related note, Romney’s campaign has a new video going after Perry on immigration.

* Jon Huntsman is closing his campaign headquarters in Florida and moving the entire operation to New Hampshire. Unless he does very well there, Huntsman will likely have to drop out after the Granite State’s primary.

* On a related note, Huntsman is also struggling with fundraising, and has begun laying off more campaign staffers.

* Newt Gingrich, who is apparently still running for president, unveiled his 21st Century Contract With America at an event in Iowa yesterday. The disgraced former House Speaker has described the 26-page document as “very visionary.”

* For whatever reason, Rudy Giuliani says he’s still considering a presidential campaign. Stop laughing.

* In Indiana, far-right opposition to Sen. Dick Lugar (R) hasn’t gone away, and the Tea Party Express will support his primary challenger, state Treasurer Richard Mourdock.

* Speaking of Tea Partiers, FreedomWorks is intervening in Nebraska’s GOP Senate primary, throwing its support to state treasurer Don Stenberg over Attorney General Jon Bruning.

* And in Florida, Rep. Vern Buchanan (R) flirted with the idea of a Senate campaign, but has now officially decided to skip the race. He will, however, seek re-election.
