I'm not sure either is true. As for the trifecta, I think the Dems will take back the Senate this election. (Well, probably will lose it in midterms as that is their calling card.) As for obstruction from the House, with Bernie as president, yes, there will be. How he wants to institute his programs will meet with a LOT of push back and Bernie is like Trump in one aspect ... he's a 'my way or the highway' candidate. And while some might think it's staying his ground, and not giving a 'moral' inch, the result is nothing accomplished. It's kind of how his entire career in Congress has gone. I have no faith that with him as president, it will be any different. Clinton on the other hand, is a warrior. She'll push back, too, and she'll work to get things done. She knows how to compromise, and in true fashion will be characterized as giving in, but while it won't get her as far as some people want, it will at least be incremental progress vs none at all.
