There are 3,141 counties in the United States.
Trump won about 2700 of them.
Clinton won 420.
There are 62 counties in New York State. Trump won 46 of them. Clinton won 16. Clinton won the popular vote by approx. 2.5 million votes. If you were to remove top most populated 100 counties then Trump would have won the popular vote by about 11.5 million.
In the 5 counties that encompass NYC, (Bronx, Brooklyn, Manhattan, Richmond & Queens) Clinton received well over 2 million more votes than Trump. (Clinton only won 4 of these counties, Trump won Richmond)
Therefore these 5 counties alone, more than accounted for Clinton winning the popular vote of the entire country.
These 5 counties comprise 319 square miles.
The United States is comprised of 3, 797,000 square miles.
When you have a country that encompasses almost 4 million square miles of territory, it would be ludicrous to even suggest that the vote of those that encompass a mere 319 square miles should determine the outcome of the election.
The above figures highlight the divide that we have in this country between urban and non-urban people. As I have stated before the problem the Democrats have is their voters are densely clustered in urban centers. If you removed California and New York from the voting totals Trump would have easily won the popular vote. I know you cannot do that but I am using the point to show the larger point.
The Founding Fathers set up our electoral system for this very reason. They were afraid that the city voters in Boston, New York and Philadelphia would overwhelm the rest of the country. They recognized that even then the people living in different states had very different interests and concerns.
Does anyone think that the voters in Wyoming, Idaho, Nebraska or Mississippi have the same major issues as those in California, Massachusetts, New York or Florida? That is why the Electoral College was established: To protect the rights of the political minority and to ensure that each state had a voice in our electoral process. For that reason each state holds a popular vote within that state to determine states electoral votes. Two states, Nebraska and Maine break it down further and use the vote by Congressional district. It has worked for over 200 years and will keep working.
