Deep in the heart of Netroots Nation, Ken Bone was greeting conference-goers at a booth.

Bone, a viral sensation from the second presidential debate between Donald Trump and Hillary Clinton, was at the annual progressive gathering as part of his gig with DonorDex, an app that connects political candidates with donors, helping campaigns “build a giant contact list of politically like minded people,” according to Bone. As the app’s spokesman, he wants to help cut special interests out of politics.
