Says the man who's never lived in the Soviet Union.
I think you will find it far less different than you're willing to credit. There will still be a big, expensive, and wasteful government that intrudes on our liberty and disregards the constitution. The only difference will be which liberties they intrude on more than others. So once you realize Democrats and Republicans are two sour apples hanging on the same statist tree you see it really doesn't matter which one you are forced to eat.
Edit: I'm sure a lot of Venezuelans thought if they elect a socialist things wouldn't be that different, now they're eating their pets.
The ultimate aim of the Democrats isn't the Soviet Union. In the US most socialists favor the Democrats but most Democrats are not socialists. Socialism is not the aim of that group. Oh sure they will talk about it, even borrow ideas from it. But like I told Ben once they may flirt with the ugly red-haired girl, but they won't marry her.
But as I have said many times and stand behind, the love of liberty does not abide in the US Democrat party. They do not value things like individual rights and freedoms. The Republicans are a best a tepid defender and sometimes and opponent of these ideals but the Democrats are antagonistic to them. Hence the reason I will never, ever, vote for a Democrat under any circumstance. But their dream society is not the USSR. It would be a USA with powerful corporations that buy favors from a government they control with a lot of power over a population that does business with those corporations and offers no dissent.
I'd couldn't even guess what the Republicans want. They don't even seem to know themselves.
