Congress cannot concent for the same reason congress cannot concent to preventing african americans from voting. The whole reason for the constitutional level of law is to prevent congress, the states, or the people from doing certain things. Things like (states) entering into treaties with eachother. Another thing to remember is the words "popular vote" never appear in the constitution. The mechanism that elects a president does not take into account the existence of a "popular vote." In the event that a state chooses not to have a popular vote for president (something a state is entitled to) this californian guy's idea fails. If it is desired to make this kind of change to the way a president is elected, you _must_ ammend the constitution.
