Those people don't know jack shit about Rand Paul. Rand is actually much closer to Mitt's idealism and that's why he's come out to support him.
Rand doesn't hold all the views of his father.

I have a couple friends who work at Capitol Hill (unfortunately) representing Barbara Mikulski. What I have consistently heard from them is that both Democrats and Republicans dislike Rand Paul and largely because of his idealism (ie. unwillingness to compromise) and strong libertarian ideology.
That does not excuse something like backing Mitt Romney, but I do not think it is that big of a deal. If Rand Paul's worse sin is backing a non-libertarian candidate in an election where a libertarian cannot win, I can deal with that.
