I think this is fair. The democratic primary is either going to end in absolute chaos, or Biden or Sanders will get an early lead and run from there.
With any of those results they end up with a candidate that has either very little voter enthusiasm, very little media support, or both.
And American's do love a good 'four more years'.
A small amount of optimism can be found in the fact that it's not hard to imagine that these people could die before the election. Bernie's heart stent could make the difference here. Following Trump, Biden, Bloomberg and Warren all keeling over, I can see him defeating Pence.
