third parties would only really have had a shot in the big states; and that's depends on the method that they use to allocate the votes - Saint Lagne would give more smaller party electors that D'Hondt for example.
There actually wouldn't be that many smaller parties represented - just done a quick check using D'Hondt and in California there'd be one Johnson and one Stein (35 Clinton, 18 Trump); one Johnson in Texas (20 Trump, 17 Clinton), 1 McMullin in Utah (3 Trump, 2 Clinton), none in New York and most of the other states are too small for third parties to be near. Probably would be close overall; Trump probably still edges it though - I might actually go and fully do it when I get some from work tonight.
If you set a 10% threshold (which is only reasonable), then only McMullin's counts, I believe. Third parties shouldn't get free EVs for simply existing in California. 10% is arbitrary, but it's a nice, round number that indicates a divide between success and failure.
