"There is a big difference between Ron Paul and Rand Paul that appears to be missed by many. Ron Paul was not hungry to be president of the United States. If he would have been hungry, he would have booted his grandson in-law and that entire gang out early on in the primaries when it was clear they were positioning themselves not to advance Ron Paul and liberty, but to advance their own careers. Ron Paul just wasn't that hungry to do that and be president. He was satisfied getting the libertarian message out.
Rand Paul is different. It appears that he wants to be president. Wanting to be president changes a man, wherever they start off from.
