In a lot of ways I agree with you on the popular vote for election of president (although I stand firmly for a thorough debate on the topic before any change to the current system is made). As it stands now, I would agree that the Electoral College process is hardly a "fair" system. I would imagine that California is much like Oregon in terms of its presidential election voting patterns. The last time a presidential candidate won Oregon's electoral votes was in 1988, which effectively means that no Republican votes for president have been "counted" in over 30 years. That's hardly "fair" yet that's what the current electoral college system brings about. There are certainly many Red states where the opposite is true.
The EC is established by the Constitution so changing to a straight popular vote election would require a constitutional amendment. Politics being what they are, and the constitutional process for amendment being what it is, that's unlikely to happen. The current end around move by Blue states to give all of their electoral votes to the winner of the popular vote has multiple problems, as discussed above in this thread. There's no reason that states couldn't distribute their electors based upon the popular vote in each state election. That doesn't require a constitutional amendment and two states (Maine and Nebraska) already do that. The problem with that, of course, is that each state is independent and can do whatever it wants with its electoral vote process. States where one party has had control for many years are unlikely to give up the iron fist that the dominant party has on its electoral votes. Even if all states agreed to go to a distributional system, there are many ways that it can be gamed to the advantage of one party or the other. See this site for an interesting interactive map:

Bottom line, if you're looking for "fair" politics isn't your game. In my view, despite all of the consternation that occurs each presidential election cycle when the "wrong" candidate wins, nothing is going to change. The basic problem is the political party process itself. That least democratic of American political institutions is not something that the Constitution mentions or that the Founders even considered. IMO, the notion that two dominant parties should control the entire political landscape in this country is the biggest impediment to the notion of one person, one vote "fairness" in the governance of this country.
