Bernie Spent Most on NY Ads, Trump Spent Least

Hillary Clinton, Bernie Sanders, and Donald Trump all have strong ties to New York, and they all approached their campaigns in the state very differently.

A report from the Center for Public Integrity shows that, in dollars spent on radio and TV ads, Bernie Sanders spent about $9.03 per vote in New York. Hillary Clinton spent $3.62, and Trump only spent $0.13 per vote.

However, those numbers don't take into account earned media. Other Republican candidates have regularly outspent Trump on ads, but in February alone, "Trump earned $400 million worth of free media."

According to the New York Times, Over the course of the campaign, he has earned close to $2 billion worth of media attention, about twice the all-in price of the most expensive presidential campaigns in history. It is also twice the estimated $746 million that Hillary Clinton, the next best at earning media, took in. With help like that, it's hard to see why he ought to spend competitively on ads.
