“Destroy the two party system by requiring that the winner of the presidency get a majority of votes. If no one gets a majority, then the top two have a run off.”
No, we should not move to a popular vote system. The Electoral College needs to be preserved. It is the most brilliant manner of choosing an executive yet devised.
The Electoral College is a assembly of representatives that sits for one purpose, to choose the president...the people indirectly choosing the president instead of directly...to preserve liberty and avoid popular tyrants.
The electoral college also mitigates the tyranny of the masses. Without the electoral college, sparsely populated states like Wyoming, Nevada or Montana would have even less voice. All power would be held by major population centers like Los Angeles, New York, San Francisco, Chicago, Boston, Seattle, Atlanta...are any of these cities being run to your satisfaction???
It could be improved by getting rid of the electors and awarding votes by congressional district. One vote per congressional district carried plus two more for carrying the majority of a state's districts or winning the state's popular vote if there's a tie in the by-district tally.
That would eliminate the faithless elector problem.
More important, it would firewall electoral fraud and reduce the influence of urban cesspools. Consider Indiana. Once the 'Rats mange to stuff in enough fraudulent votes to steal Districts 1 and 7, turning out additional deceased Gary and Indianapolis residents wouldn't help them steal the state. Instead, the other seven districts would go GOP, resulting in 7+2=9 electoral votes for the GOP and 2 for the 'Rats. In the current system, if they can stuff enough votes in Districts 1 and 7 to swing the state's popular vote, they get all 11 electoral votes and screw the farmers out in their corn fields!
The Electoral College is the 538 dedicated party activists elected by us by states from among party slates.
National Popular Vote preserves the Electoral College.
The Electoral College will still choose the President.
The candidate receiving the most popular votes from all 50 states (and DC) would get all the 270+ Electoral College votes of the enacting states.
