My sister sent me this link to a civics quiz, placed on the internet by a group that seeks to increase America's civics knowledge:
Take the quiz. See how you do. Let me know. Then when you get your results be sure to take a look at the link that takes you to a comparison of scores based on whether the quiz-taker is or has been an elected official.
To me, I'm afraid, the results are not unexpected.
I'll leave my score in the comments so you can take a look after you've gotten yours.
