Can Rubio Finally Push Bush and Kasich Out?

Amy Walter: “What Rubio needs more than anything, however, is a solid victory over his “establishment” rivals Jeb Bush and John Kasich. A solid showing in South Carolina by Rubio would put intense pressure on both, but especially Bush, to drop out. Should Rubio fail to get past Bush by a significant margin it would suggest that: 1. endorsements are meaningless these days; and 2. Rubio has deeper, more fundamental problems than just Bush and Kasich standing in his way.”

Tim Alberta: “To be clear: Rubio’s expectations are rightfully high here not just because he has these three influential state Republicans in his corner, but because his campaign has deep roots in South Carolina and always viewed it as Rubio’s best chance to score an early-state victory.”
