If Bernie (or Hillary) wins, its a matter of time before the Congress flips. Because that means long term bad news for the Republican party. Their chickens should be coming to roost right about the end of 2016...and we can finally choke them to death on thousands of tons of feathers in the shape of an omnibus bill that address all the issues they've been kicking the can for. They can threaten to shut down the government again after the election, but that trick won't work and they will either have to vote or obstruct and eventually vote, which will fuck them with their bases, and they will not be around in the next cycle.
But if Bernie wins we know that a necessary balance of power will take place in wall street. Something that we know will 100% not happen with a Clinton presidency.
