The one way I could see this happening:
--Republicans become a slightly more sane version of the Libertarian party
--Democrats abandon socialism
--Democrats become the family values party
--Some really popular governor from Wisconsin runs
Liberal Republicans, IMO, tend to be against tax cuts.
depends. right now I'd say that they might be, since we're selling off our empire in chunks to the highest bidder. Generally conservatives are tightwads, liberals are big spenders. By definition. But the manifestations thereof can be subtle. I'm a tightwad in the sense that I always pay my bills on time. I never by things on credit, never leave a balance on my credit cards, pay my auto insurance in one big lump payment per year, never let my substance connection front me anything, etc. But that's just the kind of paranoid conservative I am. A more liberal republican may live on the edge, high-interest credit card debt, get under another new car payment, 2nd mortgage,etc.
So, extrapolating to a national level. I'm a big fan of paying down debts. Leave taxes alone, even increase 'em if necessary. And that is certainly not coming from a "liberal" place in my being. It's prudent, and conservative. Also, I'll add, since I haven't posted in quite a while, that my conservatism is precisely what lead me to protest US military involvement in Iraq. Still think it was a bad idea. But, hindsight's 20/20. And it conservatism that leads me to think Bush should be reelected precisely because Iraq has become such a bloody hell.
A *really* conservative republican would probably be voting for Badnarik about now. Bush has become quite the big spender. A liberal Republican, if you will.
