this is a hot debate. Depend on chance...
Al Gore won Popular votes but George Bush won Electoral votes. That was the year we will never forget. Recount... Recount... Recount... forever mark our history.
It would be nice if system was set up to count fully down to popular votes because its more of true numbers of people wanting.
However, if you look at primary election for president candidate. Democrat use full popular votes to determine best candidate while Republican use win all even if they had less popular vote. Republican already announced president candidate and had to wait forever to see Democrat to decide who wins. It could affect the voting in Nov... Longer it takes to count, the more borderline tip over to one side than other.
Popular vote takes a lot time to count all votes. It could worth the wait. It depend on which side you are. Its falls in your favor or falls to your opponent.
