Funny, the cumulative polls here at this point in time tell us that they are both behind Hillary.

Rubio seems to poll the best one on one against Hillary.
Current polls mean nothing. Hillary will not be able to withstand the relentless assaults on her character and past criminal conduct. There is also a civil RICO cse against her ging to trial in January, and the judge has already decided there will be no further delays. When they get Hillary on the stand, her, “I can’t remember” answers are not going to fly.
