They mention that they targeted three kinds of voters, but two of them were pretty much the same kind.

From the outset, the campaign set three targeting priorities. There were “re-engagement targets” – voters who had supported Obama or Biden, but were infrequent voters who needed persuasion to vote and to vote for Biden and then Harris – mostly younger voters or voters of color. There were “traditional swing voters,” these are voters who have largely moved towards Democrats in the Trump era, mostly college educated suburban voters who were not field targets, but were tracked for support.

The third and smallest target group was “peel-away Trump voters,” who had perhaps voted for Trump in 2016 or 2020, but may have been with Democrats on abortion or who were alienated with the chaos and corruption of the Trump era.
