The Koch Brothers are like all the rest of them. They will use either, or both sides, to get what they want. None are Patriots. Some Americans are Patriots, but just spending your money on what I may or may not like doesn’t make you one.
Beware the Koch Brothers. While there are others, they are NOT friends of Conservatives.
I don't know if Koch Industries is the same as the Koch brothers but I've never noticed a commercial by KI before.
Probably the most consistently conservative big money guy out there is Foster Friess and even he is a little soft on the border.
