I think the results are the same, but the causes are different. Republican controlled governments want their programs to fail, for ideological reasons. Meanwhile, Democrat controlled governments bias for the status quo, for fear of stepping on someone's toes. This used to not be a problem due to the healthy push and pull between two similarly popular groups of politicians. But with a heavily partisan system, no group cares what the other says, so there's no pushing/pulling towards action.
