Despite some relatively lively and aggressive debate appearances from the Democratic contenders in 2016, when it came to TV advertising, the Democratic primary was relatively tame and positive. According to Kantar Media, of the 206,528 spots aired by Clinton and Sanders this year, none were considered “negative.” Trump, on the other hand, faced around a whopping $62 million in negative advertising in the GOP primary. We can expect the negativity to be pervasive as we move closer to the general election.
