The “plastic glued smile” is Tina Fey.
Tina Fey was an actress portraying a caricatured version of Palin on Saturday Night Live, a few years back, and large numbers of people became confused as a result of the widespread media coverage of the skit.
She’s not the real Palin.
Thank you, but we do not get SNL in Panama; therefore, I never saw the skit. I am going from what I see and hear live on TV news.
