I recently saw a graphic that compared vote totals for president since 1976. Outside of the last election in 2020, there has been a consistent winner:

And “did not vote” often clobbered the candidate who received the higher percentage of the popular vote, often by 10-20%.
What does this mean about “get out the vote” efforts? Is the narrative that “this is the most important election of our lifetime” effective in getting people to vote?
At the least, the presidential election turnout is better than many local elections.
