Strategic voter selection
Abraham Lincoln and his Whig colleagues had a clear strategy for gathering votes in the run-up to the 1840 elections. Operatives were instructed:
1st. To divide their county into small districts, and to appoint in each a sub-committee, whose duty it shall be to make a perfect list of all the voters in their respective districts, and to ascertain with certainty for whom they will vote … 2nd. It will be the duty of said sub-committee to keep a CONSTANT WATCH on the DOUBTFUL VOTERS, and from time to time have them TALKED TO by those IN WHOM THEY HAVE THE MOST CONFIDENCE, and also to place in their hands such documents as will enlighten and inﬂuence them. 3d. It will also be their duty to report to you, at least once a month, the progress they are making, and on election days see that every Whig is brought to the polls.
