The 2000 election is mostly known for the vote count showdown in FL (and ultimately - the Supreme Court) which resulted in not all of the votes being recounted, and Dubya getting
elected president. This precipitated a move away from "physical" voting methods (to eliminate hanging chads, etc) to electronic voting machines. The 2002 election was the first large-scale debut of the voting machines, and - from some reports - the test run for hacking the machines (somewhere, I have am encrypted zip file that purportedly contains the hack that stole the GA Senate election from Max Cleland). When Dubya was re-elected in 2004, there were widespread reports of voting machines changing votes, and concerns of hacking.
In 2008, liberals turned out en force
to assure that - even with
hacking - the election would not be stolen. President Obama won that election and his reelection.
