The Secret To Sarah Palin's Pitt Bull Attitude: Sexy Underwear?

Sarah Palin's porn alter ego Serra Paylin has told reporters that she thinks the politician's power comes from her lingerie.

Serra - also known as porn star Lisa Ann – recently paid tribute to the US Vice Presidential Candidate by adorning glasses and a suit for an adult movie cannily entitled Who's Nailin' Paylin?

The 38DD 'actress' tells Marie Claire that she's sure Sarah must wear a, "really cool sexy panty with a nice matching bra."

She adds, "I think she probably feels in power by having something sexy on underneath. She's attractive, and she puts her sexiness out there."

Lisa Ann's friends can expect a pleasant surprise when the porn star shows off her best political moves this Christmas.

"I'm planning on giving the video to all of my pro-McCain friends for Christmas," she reveals.
