“Do the math.
More of the bigger electoral vote state have bigger cities and tend to go Democrat. 40% of CA and NY.”
Just intuitively, if states divy up electoral votes based on their own popular split, the sum of doing this in all the states will essentially equal the national popular vote...which would have certainly meant a Bush loss in 2000.
The electoral college essentially becomes a middleman, in what is essentially a national popular election.
Again, do the math, I have.
States with few electoral votes tend to be conservative and the split tend to favor republicans.
