No proof or evidence that paul has attacked corruption by formally being a republican. paul has already been easily shut out in gop and there has not been much'scrambling' as you claim. media can only ignore those candidates that don't have much of a platform or background that appeal to people.
huntsman never made it far. paul already has over 15% of the nat'l vote if he were to formally claim to be libertarian/independent as all polls have consistently shown for several months. that gives him the right to be in the debates in the general election if he were an independent. however, paul supporters don't want him to be in the general election in this way - and that is the best way to take corruption head on.
your goal is purely ideological and not governing, hence you want to be make sure you are attached to not conservatism, but romney.
