Wow. You missed every last point, from the finest to the broadest detail.
The Democrats already always win California. That means they already get 100% of the electoral vote from California. Any apportioning to the national winner would give the GOP a chance to win California, without even campaigning there.
No, you are missing the forest for the trees. Undermining the electoral college system by having the President selected by the popular vote is not a good thing, especially for Reps and their Red state base. We are not just talking about California. Please read what the National Popular Vote Plan is all about. There is a reason why the New York Times, Chicago Sun Times, Los Angeles Times, Sacramento Bee, and Minneapolis Star-Tribune endorse it.

And they will continue to win California by increasing margins as it becomes more and more Hispanic. The Dems can focus more on California to increase turnout and the margin of victory, which could translate into a national victory in the popular vote. If red states like Colorado, Arizona, Louisiana, and Missouri sign on to these compacts, it will mean that their electoral votes will go to the Dems even if the Reps win the popular vote in the respective states. Gore won nationally by 500,000 votes, but he won California by 1.3 million.
The National Popular Vote movement is a way to circumvent the electoral college and have the President elected by the popular vote. The Dems tried to get Colorado to apportion its electoral votes similar to Maine or Nebraska. They would never want such a system for California. They want a winner take all apportionment there.
I am surprised that you don't understand the implications of what is being proposed not only for California but the rest of the country. It will make Dem states like California and New York much more powerful in terms of affecting the outcome of national elections. The Dems can concentrate on the most populous states to get out the vote and increase the margin of victory. If they have their way, the electoral college will become meaningless.
