He isn't treaded fair by the media.
He won a straw poll - no coverage. Another candidate get coverage for a second place. WTF?
He appears to have consistent principled integrity as Jon Stewart already mentioned. He speaks the same for 30 years and nobody was listening.

I admit the more I read from him the more I think I understand his point of view. And it makes sense all though it is not comfortable.
I also know: He is the only veteran within the presidential candidates and will bring the troops home.
Ron Paul cured my apathy in politics as an skeptical atheist. His voting record is as far as I know 100% pres-team. He never voted against the constitution. He is telling the truth about the war on drugs as well as about the foreign policy.

Imho these are examples of impressing grass root videos that might make you start to re-think your politicial believes:

"Let it not be said that we did nothing." Ron Paul, he is imho necessary.

At all I don't allow MSM to choose my presidential candidate.
