A frequently asked question about National Popular Vote is whether heavily populated metropolitan areas would be favored over rural areas in a nationwide popular vote for President.
In a nationwide election for President, every vote would be equal, and the winner would be the candidate receiving the most popular votes.
This is exactly how elections are run today inside the dozen or so battleground states where candidates currently campaign.
If there were any tendency for candidates to overemphasize big cities or ignore rural areas, we would see evidence of that in the way campaigns are conducted today inside the battleground states.
In the 2012 and 2016 presidential elections, the biggest metro areas of the battleground states actually received a combined total of 191 general-election campaign visits—compared to 188.2 visits, if visits had been based strictly on population.
