Rubio's Campaign: Should he stay or should he go?

This question answers itself. From 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.

While I can appreciate the virtue of ignoring naysayers, when this is coming from your sycophants, it is time to call it a day. Or get new sycophants.
