I think the current administration puts the lie to that idea. So-called Republicans have both houses and the WH and can't find their ample posteriors with both hands and a road map. Winning is killing them. Democrats need to pull themselves together and stick to the core ideas they've been advocating for years, and, if they regain influence, not go off tilting at legislative windmills like trying to pass single payer while the health care system needs immediate repair.
