It is fun. Video tape brings up a whole different challenge. You have to realize, I'm sure you do, you are much more proactive with respect to educating yourself than the average person.
I have 2 articles for you, one that clearly states you can criticize Obama as you wish on this site, I'm sure you are happy now!
