Democrat politicians are united in purpose. They all want to do whatever it takes to increase the size and power of government.
The Republican party is split between those who want to decrease the size of government and put the Constitution back on the throne and politicians who just want to be somebody. If the "be somebodies" can't somehow be purged from their positions of prominence in the party, the only solution is to give up on the Republican party and start a new conservative party. For all the elections Republicans have "won" in my lifetime, those of us who want smaller government have never won a thing and I, for one, am through being a loyal Republican.
