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:
* The Santorum campaign, meanwhile, has released a full schedule of upcoming campaign events to counteract rumors of his withdrawal.
* In Massachusetts' closely-watched U.S. Senate race, Elizabeth Warren raised $6.9 million in the first quarter. That's more than double incumbent Sen. Scott Brown's (R) total of $3.4 million.
* In Wisconsin, former Rep. Dave Obey (D), an influential figure in in-state Democratic politics, has thrown his support to Milwaukee Mayor Tom Barrett (D) in the gubernatorial recall race. Barrett is facing former Dane County executive Kathleen Falk in an increasingly contentious primary.
* Newt Gingrich's presidential campaign is running so short on funds that he conceded yesterday that he's been forced to do some self-financing.
* The Republican National Committee appears to have successfully turned around its financial difficulties. In the wake of the Michael Steele era, the RNC has raised more than $110 million over the past 15 months and retired more than half its debt.
* And the Romney campaign, well aware of the former governor's unfavorability ratings, released a new video narrated by Ann Romney, intended to put the candidate in a more favorable light.
