One can hope.
If this election doesn't convince people to start looking outside the two parties, then I don't know if anything will.
For starters, the Major parties have presented voters with the false dichotomy of a "two party system" for so long, people don't even think to vote "third" party. I'd bet a lot of them have never heard of the Whigs.
Many more have been convinced to vote for one of the big two because they are the big two and their vote would be allegedly wasted otherwise. How much the American Political landscape would change can only be speculated, should the voters just vote for the person they thought best, regardless of affiliation.
There is that contingent who would vote straight party ticket, regardless of who was on the ballot, whichever party they support, without consideration of the candidate.(the 'go, team, go!', mentality).
There are over 70 different parties in the US, most of which are barely footnotes, but a few which could rise to prominence. The Libertarian Party (largest, most well known, third party, based on something between Liberty and libertine, imho), the Green Party (totalitarian socialism with an ecological bent), the Constitution Party (with the US Constitution as the basis for its platform), and others. (look down the right sidebar here for a list of 'third' parties websites, and these are not all of them:
