But you cannot go far. Because of the need for the Republican party to win it had to liberalize a bit in order to garner a majority. They are riding the fence closely as the 2000 election revealed.

It is quite simple.
Lead, follow or get the heck out of the way. We must win to keep the rat infestation out. That is politics, not principles.
By becoming rats ourselves? No thanks.
