Some Rubio advisers say get out before Florida
Washington (CNN) A battle is being waged within Florida Sen. Marco Rubio's campaign about whether he should even remain in the Republican presidential race ahead of his home state primary on March 15, sources say.
Rubio himself is "bullish" on his odds of winning the critical primary, despite some advisers who are less hopeful and believe a loss there would damage him politically in both the short- and long-term.
