Airwaves in Iowa and Nevada were crowded with political advertisements before, during, and after the Super Bowl. Bernie Sanders and Elizabeth Warren each aired new local tv ads. Bloomberg and Trump aired new national ads. Bloomberg was up with a :60s ad and Trump was up with two :30s ads, though only one aired during the game.
Other advertisers on the above list were up with previously aired ads. Most were on air during pre and post-game programming, as local spots went for an average of $15,000.
