More Americans vote for the Democrats than the Republicans. If not for gerrymandering, we'd be a 1.5 party country.
Interesting concept, gerrymandering. Invented by Democrat Elbridge Gerry. Ah you "modern" Democrats, denying your own. But it's clear that Harry Truman couldn't hold a Democrat Party membership card these days let alone be nominated by The Party for president. Though Leon Trotsky would be a shoo-in.
Neither Truman nor Trotsky nor anyone else could hold a "Democrat Party membership card". There's no such thing, since there's no such party.
