The Pew Research Center has published a poll showing the awareness of issues in the public realm. Here is a breakout by Republicans, Independents and Democrats:
What I find really interesting (discounting the fact that Republicans scored higher on all but one issue) is the knowledge base of Independents is higher in all areas than Democrats except for Party in Power, Public Option and the spending on health care issues. And all this time, my Democratic friends like to remind me of how smart their friends are (since they can't seem to answer basic questions, they always refer to someone else who is smarter than they are) and that they have superior information.
Seems to be the culmination of the self-esteem generation.
