You are FULL OF SHIT, IGNORANT SLUT.
Any democracy without a constitution is no democracy. This bullshit about a constitutional republic is only to serve little gerbil brains like yours in the south.
Greece, for example has always had a constitution. And it is a democracy, and it is one man, one vote, and it has a parliament, similar to Congress with elected officials that make the laws and the rules, and an independent judiciary, and you are a jerk.
One man, one vote means nothing more than no ones vote is more than anyone else's, and without it you have nothing. We do have one man one vote here, except by state, and that is a problem, as witnessed by a popular vote where Hillary has more than 2 million votes than the jackass called Trump. The results of the previous occasion when this happened were DISASTROUS. I just don't know yet what kind of disaster we'll have this time. But, we will.
