OK, so if there's something with a pug in it, I know about it.
Actually,
this clip is from a East Coast show and the pug that is featured is someone who posts on my pug board. The clip only shows 2 of the candidates so I'll have to fill you in on the others.
Here's the answers:
McCain - Pug (I'm still not voting for him)
Huckabee - Beagle
Clinton - Labradoodle
Obama - Great Dane
