The Republicans are not the problem. Kicking them out will not fix what is wrong with our socioeconomic system. To succeed, we would have to roll back everything since at least Reagan and then go farther than that. If we do not fix the money<->politics game, even full D control of every part of government will not be an improvement, because they will just keep putting more scotch tape, bubblegum and bailing wire on the cracks in a deeply broken system.
We will have an enduring, worsening catastrophe that will eventually lead to robespierrean levels of upheaval. Sadly, it will most likely lead to the end of a Who song – Meet the new boss, same as the old boss. As you can tell, I am not getting much in the way of optimism vitamins in my diet.
