South Carolina Republican primary beyond Trump

If you want a Marco Rubio baseball cap or a Ted Cruz T-shirt, Marty Miller is your man. He's traveling America with his campaign sale. He says he won't be around much longer, but he's fearful for his kids. "The way things are going, they're going to be in trouble." His speech - and his merchandise - showcase how fractured the Republican race is.

Marco Rubio took second place in the Republican vote, beating Ted Cruz by less than two-tenths of one percentage point. In his victory speech, Rubio evoked Ronald Reagan, and continued to cast himself as an alternative. But how long will he be able to do so without actually winning a vote?

Touted as the moderate alternative after a strong second in New Hampshire, John Kasich took fifth place in South Carolina, ahead only of Ben Carson. The Republican governor has long been seen as a reasonable alternative to the "political outsiders," but many pundits say that has been exactly his weakness in this race.

Ben Carson has vowed to continue in the race, despite only having secured three delegates and all of them in Iowa. Here with veterans, the neurosurgeon campaigned throughout the state and took home the award for best statement of the night, saying he had "received as many delegates in South Carolina as all other candidates but the winner." He's correct: Trump is set to win all 50 delegates.

Initially there were 17 names in the Republican race. But even after South Carolina, it's unclear whether one of the remaining five candidates can unite GOP voters. But the Republican establishment seems to be rallying behind Marco Rubio, viewed as a candidate able to win across the board, including young voters like these supporters at his rally in South Carolina.
