If he was still capable of using the bully pulpit (and if he had ever been seriously interested in using it at all), he could start at the beginning and focus on one section at a time over the course of weeks. Instead he's telling Americans to read something that is simultaneously dull and hateful with no context.
This would be perfect as a podcast. Just break up the document section by section and do a whole series on it. Detail what Republicans want to do, why it's evil shit, how they want to accomplish it, and then draw a contrast between what Democrats want and what Democrats intend to do instead and what they need to accomplish it. Could go section by section in as much depth as you want. End each episode with a preview of the next one, start each episode with a "last time on Dragon Ball Z" recap of the previous one.
People could get this information while driving or doing the dishes or folding laundry. Instead of expecting them to sit down and read the unabridged and un-annotated "How We're Gonna Do a Fascism" by the Heritage Foundation.
Whether or not they would listen to such a podcast, who can say?
