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 expected, Elizabeth Warren officially kicked off her Democratic U.S. Senate campaign in Massachusetts this morning. She explained in an announcement video that she’s running because “middle class families have been chipped at, hacked at, squeezed and hammered for a generation now, and I don’t think Washington gets it.”

* As if Democrats weren’t having enough trouble recently, the Republican National Committee outraised the Democratic National Committee, $8.17 million to $5.5 million, in August. It was the RNC’s best-ever off-year August.

* Republican presidential candidate Rick Perry said Monday night he only received $5,000 from Merck, which makes the HPV vaccine Perry supported. It turns out, the pharmaceutical company actually contributed at least $30,000 to the Texas governor.

* In a week filled with fairly high-profile endorsements, this one may be the biggest: Nevada Gov. Brian Sandoval (R) endorsed Rick Perry’s presidential campaign yesterday. Nevada is a key early contest where Mitt Romney has been heavily favored.

* North Carolina’s state legislature will allow voters in May to consider an amendment to the state constitution banning marriage equality. It is already against the law for same-sex couples to marry in North Carolina, but apparently, that wasn’t good enough.

* Arizona is still set to screw up the Republican National Committee’s presidential nominating calendar, scheduling its primary for Feb. 28. RNC rules prohibit Arizona from going before the first Tuesday in March, and the state’s decision may push Iowa and New Hampshire to move up their contests.

* In Ohio, Rep. Dennis Kucinich (D) had already made several trips to the state of Washington in the hopes of possibly running there, but instead, it looks like he’ll run against Rep. Marcy Captur (D) in a Democratic primary in a newly-drawn district along Lake Erie.

* In a new Gallup poll, Republican presidential hopeful Jon Huntsman’s “positive intensity” rating is negative 1. That’s really not good.

* And still pretending he’s a credible candidate, Newt Gingrich’s campaign opened its first office in Iowa this week. In June, Gingrich’s entire Iowa staff resigned en masse.
