They could. Though that tends to be stepping into moderate territory doesn't it?

Bit of symantics I guess

@Frodly I'm not so sure states rights, or especially big goverment, were ever the real core issues. Rather they were means to an end. If you need a different method to achieve your goals you switch. For example Republicans are pushing against States rights because they oppose gay marriage. And letting states decide means you'll have some blue states where everyone will be getting married.

Of course throught history there have been third parties of varying importance. You're swinging Libertarian yes?
