Was a bit dubious of the EC at times, but now that I've looked at both sides of the argument, I wouldn't want a handful of highly populated large states to have full say in how the country as a whole is run.
And many may not remember, but states like California were Republican strongholds up to and including 1988. The period between Truman (1948) and Clinton (1992) voted Repub for POTUS every election except JFK. Those were the golden glory days of the California Republic. Since then, illegal immigration (mostly poor) and a large influx of rich/wealthy elitist east coast and Chicago/midwest transplants changed the face of both SF and metro/coastal LA dramatically. All wanting to buy a piece of the California dream at any cost (driving up crazy home prices). We're stuck with what we got now. We'll soon become a west coast version of the I-95 corridor before too long I fear. Even the R hold-outs like the OC and SD are becoming D controlled with urbanized suburbs soaking it up.
Can it happen again? Probably not for decades, if ever, I'm afraid. But if the Dems run California into the ground, succeeding in driving most middle class employing businesses out, leaving only the rich and those that "service" them, it might turn around if your kids get fed up and wise to it.
But, those in power will probably want to keep it that way. I hope you're children can afford to live here and not work 3 jobs at McD's, Starbucks and Walmart to squeak out a living? The few good paying jobs to afford the ever increasing rents and home prices will only be put up with for so long.
