Patton Oswalt (I believe it was him) had a bit recently about how you need eight years of a Democratic president to be followed by eight years of a Republican president for "balance."
In fairness he said Trump was so bad it made this unacceptable, but I really wish people would sit down and think about how fucking arbitrary this is. If you think PPACA is good progress for example, you should not then support someone for president who vows to repeal all of it because "oh checks and balances". It also grossly oversimplifies things and ignores what effect Congress and the judicial system have on molding policy.
Like we can complain about gridlock and obstructionism all we want, but I am thoroughly convinced this is what the average dumbass American voter wants based on their voting habits. Even when you break down wedge issues like gun control and the minimum wage and they support Democrats' positions by wide majorities, nothing is going to break the barrier of the philosophy of "durrrrrr I don't think the president should do ANYTHING"
This isn't balance. This is tipping over and falling down a fucking ravine.
