The electoral college count is altered every time a state gains or loses a congressman.
No sh!t. And I thought the census every ten years was merely a device to creat more government jobs. BTW You forgot senators of which each state has two. One problem which no one seems to want to address is that those states which have large numbers of illegal immigrants get more representatives than they should, i.e. states with lower illegal immigrant populations are partially disenfranchised.
