Paul has already signaled his liberalism on some issues, and his nuttiness.
It isn't much of a sales pitch anyway, saying that someone is better than some loser from the past, that is more of a hail Mary pass for the late stages of a losing campaign.
I don’t disagree with your statement that he has displayed some liberalism, and I’m not making a sales pitch. If Rand Paul becomes the nominee, and I’m not planning on voting for him in the primaries, then I will have far less of a problem than I did voting for Bush senior, Dole, Bush jr., McCain, and Romney.
