Rubio Gets Big Endorsement Ahead of SC Primary

South Carolina Gov. Nikki Haley is endorsing Marco Rubio ahead of Saturday's first-in-the-South Republican presidential primary, the AP reports. A person close to the Republican governor with direct knowledge of her decision says she will endorse Rubio at his event Wednesday night in Lexington County. Haley's endorsement was considered the most coveted among South Carolina politicians. She joins Sen. Tim Scott and Rep. Trey Gowdy in endorsing Rubio, who was in third place in recent polling in the state. (Here's how things are shaping up in Nevada.)
