In a recent press statement, Scott Brown declared that he was upset at a recent lawsuit settlement that requires the state to comply with the 1993 National Voter Registration Act (aka "the Motor-Voter Law"). The law requires states to offer voter registration when you apply for government services like a driver's license, but also social services like welfare too. Voting rights groups across the country have taken their states to task recently to force compliance.
Here in Massachusetts, one of those voting rights groups that sued the state on behalf of a woman who received welfare registration, but not voter registration, is headed by Elizabeth Warren's daughter and that has Brown crying foul. His complaint is two-fold: 1) the state is being forced to pay to mail registration information out to help welfare recipients register to vote (something it was obligated to do all along but ignored), and 2) this is a political tactic to help his opponent in the election. I guess following federal law is only important when it's convenient for our current Senator sitting in "The People's Seat".
