That's exactly why I think it may be time for a 3rd party in this country. The Ds and the Rs are getting too polarized and spend most of their time blaming the other for what's wrong in this country. Meanwhile, most of the country (probably in the neighborhood of 60-70% I would guess/hope) lies politically from the center-left to the center-right. When you have that much of the population that shares that much common ground, why not create a party that is willing to design policy that satisfies the majority of Americans and actually move issues forward. Sadly, I think the two-party system has become too much of a sacred cow to expect that enough people would be willing to risk their political careers to go down that road.
Full disclosure - I am FAR from being a political scientist, so my perception of how many people may fall into that centrist range may be WAY off, and there is likely far more to the issue of the two party system and creating a third alternative than I have considered. I'm just exhausted by the choices and the rhetoric that both sides have been giving us for quite some time, and the divide seems to be growing rather than shrinking.

Independents are roughly 40-50ish%, but of that group, you have significant portions that tend to always vote one way or the other. Someone people interpret that as them truly being Republican or Democrat, but I personally view it as individuals that in reality have say a Libertarian political view, and that is more like the Republicans than Democrats, so they will tend to always vote Republican.
The downside of the 2-party is obviously what we see right now.
The upside is, there is at least a majority of people getting views that they reasonably agree with, but with a 3-4 party system, you could end up having a decent sized minority getting exactly what they want, and the majority getting something that they don't want.
I know a lot of people are really down on the 2-party system and electoral college, but there are reasons why we have it that way. Now, I would like the 3rd parties to have a little more say, so Republicans and Democrats can actually be pushed and challenged on ideas and not just control everything completely. Unfortunately, each side is just pandering to their extreme bases.
