There are still a number of states and endorsements up for grabs for the candidates.

However, on Thursday, Rock Hill U.S. Rep. Mick Mulvaney revealed he won’t endorse another presidential candidate since Rick Perry dropped out.

“It’s really not appropriate for me to get involved with another race.  I’m happy to sit back and let the folks decide what they want to do,” Mulvaney said.  I like all the candidates.  I just liked this one the best.”

Just before South Carolina's primary, Perry endorsed Newt Gingrich.

Republican presidential candidate Mitt Romney has turned his attacks toward Rick Santorum.

The move comes after Santorum’s three-state sweet on Tuesday.

Romney has been attacking Santorum’s support for a number of earmark projects.
