Actually the ones I enjoyed the most were the gaffes by Obama and his VP but the media has covered them. If you listen to Leno and Letterman, they go only after Republicans. Is there a site that lists all the gaffes by Obama?
I don't think the Internet is that big.
Seriously, though, you can Google "Obama gaffes." And Youtube is full of videos that are composite clips of multiple Obama gaffes.
