So basically if Ron Paul won you'd have a civil war within the party between the true republicans who follow the platform of the old republican party (The Non-intervention and fiscally responsibility ones) vs the Neo-cons who believe we have enough money to sustain our agressive foreign policy whiles we're 15 trillion dollars in debt.
Might be the best way to return republicans back to their roots and disconnect them from post-9/11 paranoia .
From what I recall, Libertarianism is hardly the "original" form of the GOP. They supported government projects such as a massive trans-continental railroad, government control if personal lives through prohibition, & of course, imperialism. We should stop pretending the Republicans started ff as some great libertarian or paleo-conservative force in the 1860's.
