Just replace ‘Bruce Braley’ With Jeanne Shaheen, and Iowa, with New Hampshire, and the ad works just as well here.
Steyer has spent over 3 million in third party ads to help Jeanne Shaheen (reported so far). I expect that sum is much larger given the frequency of internet ads I see from his PAC attacking her opponent. (But then, Shaheen secretly likes big oil, so she’s as much a hypocrite as Steyer.)
