It wouldn't be one party.
In the Republican country it would be establishment vs constitutionalists. On the Democrat side it would be Socialists vs Communists. But the bottom line is that in our country, no Socialists, Communists, Liberals or Democrats would be allowed any power or vote.
I'm not sure if you're baiting me or you simply don't understand my proposal. I'm talking about two completely different countries here like the US and Mexico. At least on the right, nothing would make us happier than to never put up with liberal bullshit (like what's going on now) ever again. Let's just be rid of each other and everybody's happy.
