Both parties pretty much agree on a lot of things.. and voter fraud is ok by both parties. The dems lie all the time and the repubs lie all the time but try to clean up their act right before an election.
But it seems to benefit the Dems much more than the Repubs. Al Franken is a primary example of that by winning his first election because the Democratic Secretary of State allowed 360 felons to vote and he won by 312 votes.
