"Ron Paul won't win"
Nope, probably not. Thank our voting system and primaries and desire for handouts by most of the electorate.
"The lesser of two evils is still an important choice."
Not to me, considering the expected payoff for me voting in the presidential election is 0. Even if I lived in a state where the election was going to be close (i.e. not Texas), the idea that one vote makes a difference borders on a religious dogma. These days, we're lucky if one recount gets within 100 votes of the previous recount. If a vote is that close, it's luck, not your vote, that decides the outcome.
"Ron Paul acts weird when he speaks."
That's right, he hasn't focused most of his adult life on being slick and putting people at ease with BS. He's not like Bill, but then again if he miraculously made it into the White House, I'm pretty sure he wouldn't be messing around with interns.
I would also like to point out that G. W. Bush is a horrible speaker. Worse, he or his handlers try to improve his style, resulting in the horrific disparity between his speaking, his body language, and content every time he speaks.
Seriously, if you vote for people based on how slick they are, why were you NOT a Clinton voter?
