I refer you to the 12th amendment.

Additionally, if the popular vote was used to decide the election, you can be sure that we would have had multiple recounts seeing as how her lead is about 1.5%. I would guess that with 134 million votes, a true, accurate number could never be attained. In that case, after multiple recounts and courts cases, the congress would choose the next president about 6-9 months from now.
