Another problem with a national popular vote is disputes. With NPV, you’d have to recount the whole country. In 2000, we only needed to do Florida. If, as I suggested above, it went by congressional district, then the recount need would likely be limited to one or two districts.
I pointed the same thing out to mvymvy on another thread ...
Even states that voted 99%-1% would have to recount since each and every vote counts to the NPV and, thus, the Presidency ...
ALSO, who would pay for the recounts? Currently, the states pay for their own IF the vote differential is BELOW a certain percentage [1%-2%]. How would states with 99%-1% vote count feel if they had to pony up bucks for what is essentially a USELESS recount within their states?
Had Florida adopted proposed legislation to allot electoral votes by district, Al Gore would have won the presidential election even though he lost most of Florida's congressional districts. The only votes that would have been in doubt prior to a recount would have been the two allotted at large per state. They would have been irrelevant.
