Judging by that cover, I'd say Melania is next in line. xD

Now, I don't really agree with you; the "duopoly" is a thing inherent to Mankind. We are dual. We are binary. The duality is not an invention of Dems and Reps. It's been with us for a looooong time, and will be there at the end.

If forced to pick sides, which we are, then I'd go with the Republican party. They are much more interested in the wellbeing of Americans than nasty Dems. These last ones only care about their seats in power, and will go even to the extent of supporting dictatorships like the ones in Venezuela and Persia to achieve that.

If, which we are, forced to pick a side, we must choose freedom and democracy. The only party that fully supports such a thesis, that backs oppressed people thru and thru (even in my homeland of Venezuela, where a group of thugs have kidnapped the populace) has a name: GOP.
