I think you meant "speeches don't make a presidency". One of O'Donnell's many, well made points, was that the media covers the race ("horserace" was how he put it), not the actual work/governing, and the speeches, press conferences and public appearances are the stuff that the media emphasizes (because since that is what they get to see/cover, it justifies their own relevance), but have very little to do with actual governance.
One line on that point that I liked, my 49ers fandom not withstanding... was "You can remember what Patrick Mahomes did on the field (in the Superbowl) but you can't remember one word of he speech (after winning the Superbowl)", the correct implication being, because the speech didn't matter much, only the actions on the field did.
As an aside, O'Donnell does manage to sneak in a version of "Don't Switch Horses Midstream", which is a classic, historic incumbent campaign message. I'll see if I can find it again... but it is a 27 min clip.
Anyway thanks for watching the video, I appreciate you taking the time to do so. I know it was really long. I thought it was a thoughtful piece and I wanted to share, but I did the bullet points for those who would otherwise ignore it because of the length.
