The dems do not hate rules. The demonrats do nothing except make rules. For a long while they have even convinced republicans that making rules is a requirement for good government. They submit confusing and hugely controversial sets of new rules that would create problems rather than solve them. Then they convince republicans to allow some of the new rules in the name of bi-partisan compromise. So we end up with more confusing and contradictory rules.
Without more rules government will not grow.
