Polls Are Not Conclusive
Even a professional statistician will tell you that polls are usually simply a test of fame. Trump has an NBC television show, The Apprentice and a chain of hotels named after him. He is ahead of some other Republican candidates simply because he is better-known. In a one-on-one contest between Trump and Rubio, the former would be trounced, as Republican voters learned more about both men’s records and policy stances.
