I like Hunter, I disagree with him on a couple of things, but I have a great deal of respect for the man.
I was talking to a few liberal friends of mine the other day, and I started talking about Hunter, I knew it was a weird sign in that they didn't spit back any democratic talking points about him specifically (it was the generalized stuff), but then they just addmitted they hadn't heard of him, and didn't know who he was, they guessed he was part of the Tancrdo/Paul nitch.
In other words, on the upside, under the radar, on the downside, with a fear factor of zero and no name ID.
