That’s not really a rhetorical question.
You see, based on the above video* it’s very much an open question whether the Democratic party does understand that every single damfool thing that a liberal or Democrat says in front of a camera will get captured somewhere and then end up on a social media site dedicated to the mass distribution of entertaining, interesting, or topical video footage. If that observation didn’t compute, try this one: you know how the media loves them some Republicans/Conservatives Acting Badly footage, and will lovingly keep archives of same in reserve for just the right occasion? – Well, guess what! Technology has advanced to the point where anybody can do that, including people who do not like Democrats or liberals.
