US becoming a single-party state

Your opinion doesn't count if you don't consider yourself a Democrat or Republican.

But if you do consider yourself a Democrat or Republican, do you honestly wish that the opposing party be completely erased from the US, making the party of your choice the party with like 90+ & of the political power in the country?  Say if you're a Democrat, do you think it'll be a good idea if all the Republicans suddenly disappeared tomorrow?  Or having an opposing party, even if you don't really agree with the majority of their ideologies, will help keep things in check?

No I do not want the Republicans to disappear. While it would have a lot of benefits, I will shoot the first person who tries to take my guns, government or not.
