"We're not telling the Republican Party to endorse conservative candidates over moderate candidates or demanding that middle-of-the-road candidates be tossed from the party. What we are saying is, "Don't take our money, use it against us, and then take a haughty 'we know best' attitude." If you do, we're going to take you to the woodshed and show you why it's a bad idea."
The RNC or their affiliates do not "take our money" at the point of a gun. Morons send them their money of their own free will then expect to dictate how it is to be used.
End the problem -- send money to the candidates of YOUR CHOOSING!
