I don't actually see it as a left/right or DNC/RNC decide. The policies often look different on the surface, but in the US today both sides of either "divide" lean heavily into increasing federal authority and regulation.
RNC certainly has it's problems with giving powerful and wealthy individuals ways to avoid paying taxes. But when it comes to the litigation economy it is generally DNC causing the offense. RNC, to their credit, will often roll onerous regulation.
