There really is a simple explanation...
On the opposite side of the Earth's orbit of the Sun, there is a clone Earth which we cannot see. On that one, 'Rat votes are switched to Republican.
Of course, on that Earth, Republicans are the ones that want to shred their Constitution, and the Democrats are the Patriots.
I saw that science fiction movie!
It seems you're stuck thinking in Democrat vs. Republican; that's not the case anymore: it's patriot vs. globalist.
And you'd better believe the Republican party is in the tank for globalists, that's a big reason that as-a-party they were/are against Trump who is a nationalist and therefore against their "new world order" -- it also explains why they so desperately tried to push Cruz: he's obviously ineligible under the NBC requirement, and that requirement is so distinctly, obviously nationalistic in nature that (in the globalist's mind) it must be destroyed. (It's also why they put forward Obama and McCain, both of whom are quite questionable [at best] under the NBC requirement.)
