Social conservatives are hypocrites ... small government, except when it comes to enforcing THEIR chosen moral code.
Neo-cons are not fiscally conservative (look at GWB deficits). They are imperialist corporatists. Thankfully most on the right have finally realized this (only took them 8 years !)
Libertarians live in a fantasy world where removal of government enforced rules and regulations, reduction of taxes and elimination of government social services somehow does not lead to a society where the rich and powerful ruthlessly exploit the working classes, and where the middle class ceases to exist as we have known since WW2. They also seem to believe that the US government cannot be fixed, so it must be defunded. Interesting then that other developed nations can apparently form a better working government. Perhaps American exceptionalism mean inability to operate a working government. Go USA !
Originalists apparently see no distinction between a "well regulated militia" owning muzzle loading rifles for defense from foreign armies and the right of every citizen to carry an Uzi in the glove box, or a Glock in their pants "just in case".
IMO the American right is morally and intellectually bankrupt, and the GOP are simply the hired thugs of the rich and powerful. The left leaves a LOT to be desired, but they are definitely the lesser of the two evils.
