Yup, you don't need to change peoples' minds to affect election outcomes, you just need to encourage the right people to vote. Send messages about hot-button issues to people who are already likely to be enraged by them, and you'll get more of them turning out to the polls. A friend of mine volunteered on the Clinton campaign in the months before the election. The strategy wasn't to knock on random doors and convince people to vote for Hillary, it was to find people who are already likely to lean left (but maybe aren't likely voters), and remind them of the upcoming election and where to vote, etc. Online ads take the same approach, just subconsciously.
