Here's a fact that will blow your mind. The $300 million the Kochs plan to spend in the 2014 election cycle could replace the annual income for 5,270 American households. And it's barely a drop in the bucket of what these guys and their cronies have to draw upon to buy themselves a Congress. They've got so much money and staff invested in this—240 full-time employees in 32 states—the Washington Post Fix team determines, that they're the nation's third-biggest political party.
By the way, this is just showing Americans for Prosperity staff and state engagement, not the entirety of the Kochs' network of political groups. And really, as it stands now you might as well lump them in with the Republicans, because the Kochs really aren't interested in electing anyone but Republicans.
