New York: Hollywood actor Alec Baldwin says US vice presidential candidate Sarah Palin is "a good sport" for confronting Tina Fey over her comedy spoof.

Fey impersonated the Republican in comedy sketch series "Saturday Night Live" and has been blamed for the party's recent slip in the polls ahead of America's presidential election next month, reports imdb.com

Palin also appeared on the show in a retaliation sketch with Baldwin. The actor defended the decision to invite her on the NBC programme.

He said: "When you come on a show like that, you are prepared in advance to get worked over. Palin knew that. Palin came on to be a good sport. And she was. She was polite, gracious."
