Glee Casting Call For Sarah Palin Type Character - Tea Party and Glee?

The Fox TV show Glee has placed a casting call for a "Sarah Palin type character" for a role on the hit show.
Are they ready to now mock the Tea Party?
The character is named Tammy Jean, and described as a "middle-aged recent Tea Party candidate and home schooler — a Sarah Palin type."
However, show creator Ryan Murphy says he is not bringing Tammy Jean / Sarah Palin on the show to mock and make fun of, but to be inclusive.
“We’ve taken a couple jabs at the right wing this year,” Murphy told TV Guide last June.
“So what I want to do with this character is have someone who Christian kids and parents can recognize and say, ‘Oh, look — I’m represented there, too!’ If we’re trying to form a world of inclusiveness, we’ve got to include that point of view as well.”
“Pat me on the back,” Ryan Murphy says, “after two seasons, we’re not going to be bigots anymore!”

Liam Neeson starts as Dr. Martin Harris in Unknown

Dark Castle Holdings / Warner Bros. Pictures

You're Dr. Martin Harris, a botany professor at an American university, and you've come with your wife Liz to Berlin for a biotechnology conference. As she checks into the hotel, you realize you left your briefcase at the airport and hail a taxi, telling the blonde driver to step on it. An accident sends the cab careering off a bridge and into a river, from which the driver pulls you out before vanishing. A few days later you awake from a coma and bolt from the hospital to join Liz at the conference. Funny — she doesn't seem to recognize you. And the man standing next to her, she says, is Dr. Martin Harris.
