My prediction is yes, by 3 points, 17% to 14%. Rubio has done nothing effective to repair the damage from his debate performance. He just doesn't get it. You can't keep delivering canned speeches. You need to get more conversational, and project some thoughtfulness. Doubts about Rubio's basic competence to be POTUS continues, and will continue to drag him down, unless he does something to mitigate it along the lines of the above. That assumes of course that he is capable of the same. We shall see.
In a word, my confidence in Rubio has been substantially shaken. I wonder what Muon2 thinks. I doubt he will tell us though.
