The pharmaceutical industry has donated $589,344 to Hillary Clinton's campaign, according to the nonprofit research group Center for Responsive Politics. That's more than any other candidate — despite Clinton's proclamation that she's proud to call the pharmaceutical industry her enemy.

"Price gouging like this in the specialty market is outrageous," Clinton tweeted in September, referring to the now-infamous decision by Turing Pharmaceuticals to raise the price of a decades-old medicine by 5,000 percent overnight. "Tomorrow I'll lay out a plan to take it on."
