The fact he portrayed himself as a Reagan disciple when he actually, apparently, distanced himself from Reagan. It gives a false impression that he supported Reagan, when that was only partly true (assuming what TA posted is accurate).
I actually thought it was a good ad, before reading what TA posted, and I never agree with anything TA posts (to the extent I read it).
TA posted stuff from when Paul was running for office and every candidate had to make cases for what they felt was wrong over recent years. And indeed there were things Paul felt went wrong under Reagan, but on the principle of what Reagan originally ran on Paul did support vocally back then. It was those principles, smaller government, government is not here to help you, less taxes, all that kind of stuff that Paul did always stand with Reagan on. It's these issues that were raised in the ad. On that aspect the ad is spot on.
Ron Paul still today stands on stuff Reagan said. And look, in some instances Reagan brought this on himself, look at his speaches, he was totally for non intervention but during his admin, he blized the shit out of south america in intervention. There's all kinds of shit where Paul at the end of Reagan's time had to run against. But he still supported the ideology of smaller government, the government gets in the way type of stuff. Paul DID support Reagan on that and Reagan DID support Paul for these same ideals. These are the things that at the time Rick Perry DID NOT SUPPORT. In that aspect the ad is right.
