As early voting in the US presidential elections gets underway, ES&S iVotronics touch-screen electronic voting machines have been observed in four separate states flipping the votes - mostly from Barack Obama to John McCain but sometimes to third party candidates too. This has already occurred during early voting in the states of West Virginia, Tennessee, Missouri and Texas.

A county clerk in West Virginia invited a video crew to watch his demonstration of the reliability of the disputed voting machines but instead he saw the machine flipping the votes, as critics claimed. He put this down to the faulty calibration of the voting machine. However, even after he recalibrated the machine it continued to flip votes. Watch the video here:
