If Johnson wins here and gets enough to prevent either Trump or Clinton from getting 270 electoral votes, I legitimately wonder what the congressional delegations will do.
There are more states with Republican majorities in the House. They'll pick Trump even if he loses the popular vote by 5%.
The house can pick Johnson, constitution says top 3 in EVs. Considering there won't be any risk of electing Hillary (an absolute majority of states is required, plurality doesn't cut it), I could see the house settling on Johnson.
