The investment is a departure from Trump's tactics during the primary

Even as the candidate downplays the investment he'll make in such efforts, it is a signal that his campaign and the GOP are ready to add layers of traditional campaign structures to his insurgent bid for president.

The investment in voter modeling, described by a Trump source Tuesday, is a departure from his tactics during the primary campaign.
