I kinda hurried my test (over VPN btw) so I think I could have done better but I was -1% on D and -6% on R.
I really think the perception of the two sides even by those that are not on one of the sides is off. Primary due to the fact we overweight what we hear and see online and in media. I used to fall into this trap more than I do now. Once I became more aware of how media amplifies things and distorts things and started to focus more on the people I know and what they actually do and say I started to worry less and get far less concerned about things.
We are still new to this Internet thing. Prior to the Internet I just don't think we were exposed to so many people and how nuts they can be. But on the whole people aren't all that extreme.
