Fixing the Electoral College

I really thought I had already written this solution. But my search comes up empty. I'll try and keep this brief.

Current Problems with Electoral College
1. Most of the country doesn't have an incentive to vote as their state is already leaning one way or the other.
2. The candidates spend all their time and money in the swing states that matter

Problems with using the National Popular Vote
1. While every vote "counts," I predict that many people would think that in race of 130 million votes, their vote is insignificant
2. It's more complicated to count on election night and if there's a recount, it would be a disaster
3. Critics claim that candidates would spend all their time and money in big cities


The Obvious Solution
Keep the Electoral College but award all states proportionally, instead of winner take all.

Does it even make sense that in a state like Ohio that is split 50/50 every election, that all 18 electoral votes go one way or the other?

California has long been a solid 55 for Democrats. But that state's vote is only 57/40. If you're a Republican in CA, you must feel like it doesn't matter, but it's not like you're alone.

Plus, it would give third party candidates a chance to at least appear respectable, which is the first step toward building a viable third party.

If I had a ton of free time I'd love to go back and look at the last three elections under this system...but I don't. My guess is that each race would be even tighter.
