I took it to mean "I don't know if this is actually true or not, but I'm going to post it anyway" which is exactly where tons of quickly-spreading misinformation comes from and how it gets passed on.
Specifically, the claim that it's the popular vote overall seems off to me, though I don't currently have time to look into it (I did some quick googling but did not get a conclusive answer). What I mean to say is that, yes, all of the electoral votes are allocated to whomever is considered a winner and it is not proportional (except in two states). I was under the impression, however, that it went by districts so whomever won the most districts got the full share of votes (i.e. not the overall statewide popular vote).
