Is the vote in America so corrupt, so manipulated that it is an exercise in futility now?

Until it is mandatory that all electronic voting machines also have a paper verified ballot for recounts there will be no elections, only selections.

It has been that way from the very beginning of your country, with it's enslavement of the Black Man and genocide of the Indian. You have always had only one more party than the Soviets under Stalin.
That is why Isaac Brock died for us.

Since only U.S. citizens can vote in elections, only U.S. citizens should be allowed to contribute to election campaigns. No money whatsoever should be allowed from any other source. And, the amount of contribution from any individual, including the candidate themself, needs to be limited so that elections can't be "bought" by the elite. Media should be required to air debates between all candidates in return for the citizens allowing the media to use the public airwaves. The candidate must have a certain number of signatures in order to be a qualified candidate and eligible to participate in the debates.
