Conservatives have deeper pockets? I don’t think so. The Koch brothers are famous because they are exceptional. Most billionaires are libs.
The Tea Party conservatives got their money in the last election from millions of small donors who couldn’t stand what was happening to their country.
On the open secrets list Koch industries still gave 9% to democrats which is a hell of a lot more even handed than unions which seem to give about %1 to republicans on average.
