COLUMBIA, South Carolina (CNN) – Here's a quick look at what's making news in South Carolina politics this morning:

Hillary Clinton's campaign says they will announce a "prominent" South Carolina endorsement on a conference call at 2:30 p.m.

JFK's former speechwriter Ted Sorensen will campaign for Barack Obama tomorrow in Columbia at the Jewish Community Center.

Sen. John McCain will send out a new mail piece in the state today promoting McCain's judgment on the troop build-up in Iraq and also raising the topic of immigration, tricky territory for the Arizona senator.

Mitt Romney criss-crossed the state yesterday, holding press conferences in airport hangars and facing questions about his falling poll numbers. The State writes that Romney is seeking to "re-energize supporters." Mike Huckabee spokesman Adam Piper calls Romney "desperate."

Romney defended his ads drawing contrasts with Mike Huckabee in Iowa, and also raised questions about Huckabee's Christmas ad now running the Hawkeye state.

"I hope Gov. Huckabee like all of us at this time, is sensitive to that diversity of faith and the liberty of peoples to worship God as they choose," Romney said.

Dan Hoover takes a big picture look at the GOP race with one month to go until the Republican primary.
