I think you just said over 50% of the GOP is too stupid to vote. And sadly, I think you might be right. Not that it helps, but it is worse in the other party.
I don’t know about it being necessarily worse. For starters, there aren’t any Republicans pretending to be Democrats in the opposition (certainly not any who could get anywhere near the nomination — the GOP establishment is very happy to put up RINOs who consistently lose. They’re very comfortable having Democrat Presidents). The Dems haven’t nominated a non-liberal candidate for President since 1924 (John Davis of WV). The left went hysterical that year that they didn’t have “one of theirs” to vote for on either party ticket (ultimately, they went with ultraleftist Republican Sen. Bob La Follette running on the Progressive ticket).
No, they, for all their evil, at least have the presence of mind and guts to stand for what they believe in. We prove every election that we do not.
