Section 8 of Motor Voter is there, in the words of J Christian Adams, to bring integrity to the voting process. It forces states to remove ineligible voters (ie. dead people, felons, illegals, etc.) from voter rolls to prevent voter fraud. According to Adams, the DOJ has issued a mandate to not pursue cases that deal with this specific section of the Motor Voter law. In fact, he says the DOJ actually dismissed a case that the Bush administration was pursuing that dealt specifically with Section 8 voter fraud in Missouri.
So in effect, this administration is condoning voter fraud. Awesome.
