Ron Paul is truly the only guy who WANTS to reverse direction. Forget whether or not he could.
Cutting taxes is not reversing direction. It's tinkering in an obviously broken and oppressive system and still only slows the descent into unfair taxation.
I'll give you the Cold War, mainly because I think that was one of the best things Reagan did. But he passed gun control laws, didn't put a rein on spending, signed amnesty for illegals, and didn't work to repeal any laws. He worked within the system instead of trying to change it.
Do you really think the system is fine and 90% of it doesn't need to be thrown out? Come on, be honest. Forget about whether or not we can throw out 90% of it, name one candidate who wants to even start in that direction besides Ron Paul.
Ron Paul is for some pretty radical changes, and domestically I LUV his ideas, especially on health care. I doubt he could get them accomplished though, in part because of the communicator thing.
