BULL. Democrats would just ramp up GOTV in megacities to tip the "national popular vote" those outside the megacities in select states would have their votes rendered meaningless. A high Democrat turnout in Los Angeles could tip a compact-joining state like Wyoming to match the popular vote even if the overwhelming numbers of Wyoming residents voted Republican.
It's insanity. The entire nation would be held hostage just as millions of Californians across a much wider portion of the state are held hostage by L.A. and S.F.
Do you think the Democrats elected to every statewide office in CA care about anywhere outside those two strong holds? They don't because they don't have to.
The Founders new exactly what they were doing when they set up the electoral college system rather than going for a president directly elected by popular vote. This "progressive" reform is a Democrat's wet dream.
Even in California state-wide elections, candidates for governor or U.S. Senate don’t campaign just in Los Angeles and San Francisco, and those places don’t control the outcome (otherwise California wouldn’t have recently had Republican governors Reagan, Dukemejian, Wilson, and Schwarzenegger). A vote in rural Alpine county is just an important as a vote in Los Angeles. If Los Angeles cannot control statewide elections in California, it can hardly control a nationwide election.
In fact, Los Angeles, San Francisco, San Jose, and Oakland together cannot control a statewide election in California.
