I thought it was great. It occured to me later though that they probably intended a slight towards Palin regarding the foreign diplomacy issue when Tina said "I can see Russia from my house". At first I took it to be an understated indication that she understood that the world beyond our shores presents a very real threat. Then I realized that the writers of SNL probably don't think that way and were simply ridiculing Palin.
Looks like Mad TV went in a different direction with the Presidential Race. http://www.youtube.com/watch?v=gyDtD694JaM
Typical Tina Fey Republican bashing.Palin portrayed as an idiot while Hillary deserving the Presidency but screwed over because of sexism. Not really funny.
