Both parties work to suppress voter turnout on one another's turf.

Obama himself commented on the Acorn controversy, and admitted that Acorn had likely paid people to do the job of registering voters, which is time consuming work. Some of the people Acorn paid turned in bogus registrations, just to get the paycheck. By law, Acorn has to turn those registration cards into the state authority responsible for verifying the registration as legitimate.

Especially with the recent advances in technology, verification of legitimate voter registrations is easier than ever before. Most places in the US enjoy some of the cleanest voting on the planet.

I'm far more concerned with corporate control of the federal, state and local governments and the two corrupt parties that run those governments, than I am about vote tampering. It is a very, very minor quibble in the US, IMO.

Worry about the stuff that really matters, like how to get rid of the crooks who have taken over the US government and put them in jail where they belong, reform and regulation, changing the highly politicized, partisan environment that government workers are forced to function in--then you will see some change for the better.
