He's clearly winning people over and making many think for themselves for once. I've never seen so many on the left agree with a GOP senator like when he staged his drone filibuster.
Rand makes sense to people on a lot of issues. Would he have the same success rate if he appeared strictly as a libertarian? absolutely not.
The recent remarks by Reid that the GOP Senate is being overrun by the tea party, referring to Cruz & Paul, tells me these two are doing something right.
