, thanks, and I think you are exactly right on it--both parties do often trend toward galvanized positions to prevent looking too deeply into the lack of good governance. Though I fear the GOP extremism is rather more alarming, as it is harking back too far toward the Jim Crow politics I thought we'd moved away from.
On the other hand, at least historically, both parties also trend toward centrist positions almost as often, as well as a propensity to subsume the ideas of viable third parties and popular movements in order to maintain their political hegemony and bring more people under their tents.
It'd be awesome to see us move toward more parties that represent specific issues & demographics, as opposed to the two majors who keep everyone divided and confused. Then maybe we'd get to experiment with coalition governments and things like that, as all the interests would have no majority and would need to work together.
