Pageant Panic

In a review of a recent Parks And Recreation, Leonard Pierce writes:

...it also features the return of Susan Yeagley as beauty queen/trophy wife Jessica Wicks. She plays the role perfectly, with a combination of unctuousness and condescension so often found in beauty queens, and she perfectly nails the repulsive Southern-dame quasi-charm common to the archetype.

Does Pierce know a lot of beauty queens? I wasn't aware that they were generally unctuous and condescending. I've actually known a couple and they were both very nice people.
