Guess you have not seen the latest polls. That is no longer true.
Which polls are those? You got some secret polls that none of the major poll tracking websites know about?
You are kind of know-it-all for only being on FR 3 months.
Actually, I just looked at the last five polls and Cruz leads Rubio by 5 to 7 points in every one, although Trump leads all the others going back to August.
