It doesn't matter if you vote or not- It only matters if you count the votes or not, and who's counting them!
On November 24, 2000, as the lawsuit initiated by George W. Bush to stop a recount in Florida was grinding its way to the Supreme Court, Rush Limbaugh noted one of the more famous quotes attributed to Josef Stalin. "Those who cast the votes decide nothing," intoned Limbaugh. "Those who count the votes decide everything."
Got to get the ones counting the votes to be honest with neutral observers from other countries, like we do in other countries to prove that we have been honest with our banana republic- sorry- DEMOCKERY. Since you can't confirm a machines accuracy, it should be a priority that these tabulating systems are accountable by independant neutral observers or complete elimination of these programmable machines.
Perhaps honesty in politics will raise its head if we get rid of these items and then concentrate on getting lobbying made illegal and public funded Presidential races/convention nominations to attract a better class of intelligent politician than the lying scum mafiosa types we elect now.
