Gawd. I love the stench of false equivalency in the morning, or any time of day, really.
Perhaps you missed how Dems fussed back & forth with each other interminably over the ACA & financial regulation. How they didn't present iron clad obstructionism when in the minority in the Senate. How they don't get their campaign contributions & associated "independent" support from a very well coordinated group of billionaires & hangers on. Democrats run on a variety of positions, something that can't be said for Koch candidates.
But they're just as bad, anyway, right? It's what you have to believe to keep the faith, so you do.
