Today's installment of campaign-related news items from across the country.
* As Rachel noted on the show last night, Bernie Sanders' campaign has been raising money hand over fist since cruising to an easy win in the New Hampshire primary.
* In a bit of a surprise, Donald Trump's campaign has reportedly pulled an attack ad targeting Ted Cruz in South Carolina, replacing it with a positive spot about Trump. The Wall Street Journal reported that the shift came after aides concluded "efforts to be more positive" played well in New Hampshire.
* Rush Limbaugh didn't endorse Ted Cruz yesterday, but he came close. "If conservatism is your bag, if conservatism is the dominating factor in how you vote, there is no other choice for you in this campaign than Ted Cruz, because you are exactly right: This is the closest in our lifetimes we have ever been to Ronald Reagan," the radio host said.
* American Future Fund, a secretive far-right group, is reportedly going to invest $1.5 million in attack ads targeting Cruz, labeling him "weak" on national security because of his support for bipartisan reforms to NSA powers.
* Ben Carson, who claims he's being "pressured" to stay in the GOP race -- by whom, he did not say -- is willing to talk to Trump about possibly being the Republican vice presidential nominee. As a rule, candidates confident about their chances don't say things like this.
* No one seems to have any idea what's going to happen in Nevada's Democratic caucuses, but it's worth remembering that Robby Mook, Clinton's 2016 campaign manager, "first rose to fame in Clintonland after he oversaw Clinton's 2008 Nevada caucus campaign, where she won 51 percent of the popular vote."
* In an unexpected shift, Indiana Gov. Mike Pence (R), up for re-election this year, switched running mates this week, dropping Lt. Gov. Sue Ellspermann (R) and replacing her with former Indiana Republican Party Chairman Eric Holcomb.
