Feeling the Bern: Sanders Campaign powered by 350k donors

"Feeling the Bern" has become the favorite catchphrase for the insurgent campaign of Senator Bernie Sanders and for good reason. Seemingly everywhere Sanders goes, there are huge crowds (sometimes even over-shadowing the Donald's crowds) and now we have some hard numbers to back up that popularity: 350,000

That's how many donors have contributed financially to the Sanders campaign, reportedly more than ANY candidate in the current presidential race.

So what is behind the "Bern"?

I'll leave that to The Economist's V.V.B., who recent piece Bernie Sanders on tour:Chicago feels the Bern, gives a good idea of the "genius" (or madness) of the Sanders campaign.
