I think this demonstrates the frailty of a two-party system. If one candidate in the general unexpectedly gets knocked out, the election is all but over. Granted, the primaries remedy this to an extent, except when you have the unabashed stacking that was employed to counter recent 2012 and 2016 primary campaigns. Democracy is at its most interactive in the early stages of the election, but the vast majority of people will never leverage that opportunity. People don't act until a media apparatus cues them to cast a vote for its packaged candidate de jour.
