The Motor Voter law was supposed to dramatically increase turnout and give marginalized groups more voice in politics. Unfortunately, getting these groups to register doesn't do any good if you don't give them reason to vote.
Organize the whole state, so that every Whig can be brought to the polls . . . divide the county into small districts and appoint in each a sub- committee . . . make a perfect list of voters and ascertain with certainty for whom they will vote . . . and on election day see that every Whig is brought to the polls.
Abraham Lincoln, Illinois State Register, February 21, 1840
