When Ron Paul asked his question to John McCain last night, I didn't really know what he was getting at, but I figured it was meant to make John McCain look uninformed.
This video, while poking fun at McCain, shows that Ron Paul did indeed make John McCain look uninformed on the topic. Granted the video is making fun of McCain by comparing him to Miss South Carolina, but if you make it to the end, Ron Paul's statement explains why John McCain definitely appears uninformed about the topic.
The only problem is that I am also uninformed (as is most of America I assume), so while cunning, I'm not sure how many votes it won Paul last night. Hopefully, more than I realize.
