Not my conclusion; it's the AP's.
For as often as Democrats attack the conservative billionaires Charles and David Koch for their heavy spending on politics, it's actually the liberal-minded who shelled out the most cash in the just completed midterm elections.
At least, that is, among those groups that must disclose what they raise and spend.
Among the top 100 individual donors to political groups, more than half gave primarily to Democrats or their allies. Among groups that funneled more than $100,000 to allies, the top of the list tilted overwhelmingly toward Democrats — a group favoring the GOP doesn't appear on the list until No. 14.
The two biggest super PACs of 2014? Senate Majority PAC and House Majority PAC — both backing Democrats.
