Nobody cares, and for good reason. Moderates are losers, and they are an infinitesimal part of the Republican Party. But they always get the nomination, and conservatives always take their kicks and come up smiling. So there is a kicking order, exactly like the pecking order among chickens. The liberals are at the top.
Conservatives are at the bottom.
Moderates are in the middle. The whole point of being a moderate is that you give liberals half of what they want. For a moderate, liberals are always the ones who set the agenda. Moderates then compromise with each new liberal proposal, giving them part of anything they demand. Moderates are the liberals' crawlers and obeyers.
