While Bernie Sanders accuses Bloomberg of trying to buy his way to the nomination, the socialist bought his surge with $50 million in spending. He raised $25 million just in January. There's more buying to do.

And while he boasts of backing from small donors, the wealth of his donors is anything but small.

Google, Amazon, and Microsoft. Their employees are three of the top 4 Bernie donors. Apple is in fifth place. These dot coms are not exactly organizations known to employ members of the proletariat. Google software engineers have sent thousands of dollars, individually, to Bernie.

Google's senior engineers, like the ones who have backed Bernie, make $250,000 a year.

Geographically, Bernie's top dollar zip code is 94110 in San Francisco. The average household income in this part of the Mission District, specifically the Inner Mission, the Bernal Heights area, is $166,302. The median home value is around $1.5 million and the median rent is almost $5,000 a month.
