Today's installment of campaign-related news items from across the country.
* A day ahead of the Democrats' South Carolina primary, Hillary Clinton's campaign has unveiled a new ad leaning heavily on Rep. Jim Clyburn's (D-S.C.) support.
* Earlier this month, the Congressional Black Caucus PAC officially announced its support for Clinton, and today, the Congressional Hispanic Caucus' political arm is poised to make the same endorsement.
* Sarah Huckabee Sanders, Mike Huckabee's daughter and former campaign spokesperson, has joined Donald Trump's campaign team. Don't be too surprised if a Mike Huckabee endorsement soon follows.
* One of the key prizes in the Democratic race on Super Tuesday is Massachusetts, and as Rachel noted on the show last night in an exclusive first-look report, a new WBUR poll shows Clinton with a modest lead over Bernie Sanders in the Bay State, 49% to 44%.
* In Virginia, another Super Tuesday state, a Monmouth University poll shows Clinton leading Sanders by a two-to-one margin, 64% to 30%.
* In Florida's Democratic primary, scheduled for March 15, PPP shows Clinton ahead of Sanders, 57% to 32%, and Quinnipiac found very similar results, 59% to 33%.
* John Kasich's campaign picked up another wealthy benefactor yesterday, when Silicon Valley entrepreneur Steve Poizner threw his support to the Ohio governor. Poizner, a multimillionaire, is a former candidate himself, losing in a Republican gubernatorial primary in California six years ago.
* In Alabama's state legislature, 36 Republicans have made presidential endorsements, and 33 of them have gone to Rubio, reinforcing the larger trend: the GOP establishment just about everywhere backs the Florida senator.
