Let's keep something in mind. No one single candidate will be perfect. There will be some positions that we do not agree with, and that goes with any candidate for either party. But he has a strength and seems pretty genuine, something many of our past presidents have not had. Let's face it, those who were elected in the past were not of the most upstanding moral character, but we knew where they stood.
Gore was shady, so was Kerry, that is a main reason why they weren't elected. Obama promised changed and most people bought into it. He came across as "one of us," and most people were pissed at Bush and Republicans. This guy could be using the same strategy as Obama did (one of being a genuine guy who "got it.")
Now, if he were elected, could he stay true to his convictions? No one knows, not right now at least. We could look at his past decisions, his military experience and record, and make some kind of guess about him.
It is still too early to tell about him, but from the video, he shows some strong qualities. Most notably, one of lack of political correctness, and calling it like it is. Some good signs from him so far, let's see some more from him before we jump to conclusions.
