Ron Paul defines himself as a constitutionalist. He states they are the traditional/original republicans. Its extremely clear that he is not a Bush republican. I don't know how you can maintain they are similar.
I'm not sure what you mean by constitutionalist. If you mean "originalist" .... that's not a recommendation in my book. Originalists appear to think that what worked in the eighteenth century should work for a country of 300 million with a $14 trillion GDP. Originalists also think that a constitution is a code, which it is not.
As the greatest supreme court justice john marshall said, let the judges not forget that it is a constitution they are
expounding. He didn't say "applying" which is quite significant. It's not some rigid document that is stuck in the eighteenth century.
Why are Bush and Ron Paul similar? Well, they both like talking about complex things as if they're simple. Granted, we could use more simplicity in some areas, but in a world as big as ours, that's not always going to be possible. Both of them appear to be equally naive about that, albeit in different ways.
Running on an independent ticket does not work in this country. I hate the 2 party system, but unless there is a major change, candidates need to ally with one party or the other. We must concern ourselves with the message itself. Ron, himself, is not some great poised political icon...its the message thats important, the message of balance and common sense.
Well, since the REpublican party isn't working for him, he might as well be an independent. it's not like he would have had any less of a chance at the presidential nomination. And he does want to be a political icon. Why else does one run for president?
