I think I can safely say that The Donald is not a personal favorite of many Americans. So where does this popularity suddenly come from? This, it seems to me, is a question of vital importance to ALL of the people who have thrown their hat in the rings. The answer of course is that his ideas are resonating with the American people. And powerful ideas they are when an arguably unpopular character becomes wildly popular when he articulates them.

Candidates and other politicos, ARE YOU LISTENING?

Donald made a rookie mistake here. He should have noted that he was the front runner and that they had to go after him. He could have pointed to the early polling showing he did well and left it at that. This was petty.

Typical response from a school yard bully.
Granted, it could be an act, but if so it's an indication that Trump is wholly unprepared for the office.
Rand Paul had more to complain about than Trump.
In all fairness, the format is flawed, going for superficial sound bite answers that do nothing to qualify any candidate for the office.
In addition, the "moderators" are simpering, liberal statists who belong in a third world country (possibly a clue of US status.)
