This is a BAD move.
Voter FRAUD will determine who wins.
Voter FRAUD will determine who wins."
That's pretty much what happens today....look at the Florida Fiasco and how an attempt was made by the Progressives (aka, Communists/Socialists) tried to steal the Presidential Election, and how Franken was illegally winning his seat.
The "SOS Project" (to win as many Secretary of State positions) was solely purposed to make sure a close election count resulted in the "Progressive" candidate winning, using whatever maneuvers were necessary to tilt the election.
A National Popular vote will merely mean that Flyover Country will not matter, and NY, CA, FL, etc. will simply pack the popular vote in their handouts' favor.
Same as All-Star Baseball is packed with CA and NY players due to sheer numbers, we will have Democrats/Progressives/Socialists forever elected in National Elections, period.
This will be the impetus for movements to seceed from the Union, as being merely the source of cash for handouts in the Big States and Big Cities (aka, cesspools) will cause the people in the small states to say "we're outa here...."
I consider it completely unimportant who in the party will vote, or how; but what is extraordinarily important is this—who will count the votes, and how.
