Sarah Palin will help Bristol hawk books at MOA

Palin almost signed City Pages the last time she visited MOA.

Undeterred by a tomato thrower and the smaller-than-anticipated crowd that greeted her the last time she tried to move product at the Mall of America, Sarah Palin has booked a return engagement.

Personifying the phrase "helicopter mom," she'll be at MOA tomorrow to school her daughter in the fine art of personal brand management, as Bristol signs copies of her memoir, "Not Afraid of Life."

Mama Grizzly may lose elections and quit important jobs, but when it comes to be a shameless self promoter, the woman is a pro. Bristol's off to a good start in that regard -- Dancing With The Stars was a boon -- but she'd do well to take notes.

For example, Palin just happens to be in the neighborhood these days, shilling her own feature-length public relations movie in Iowa. So why not cut costs and piggyback two sales jobs into one! Economies of scale are important.

And remember how, the last time she was in Minnesota, Palin helped Michele Bachmann raise a pile of cash with $10,000-a-pop photo ops? You know you're a master saleswoman when you can get fat cats to lighten their wallets just by showing up and winking.

The time before that, Palin was flogging "Going Rogue," to keep it on the best-seller lists, enduring day after day of fawning praise from breathless supporters. Getting one's ego stroked on a daily basis is important for maintaining self esteem.

It also helps stave off the low points. Jeremy Paul Olson was also at MOA that day, armed with a pair of tomatoes on the second floor balcony overlooking the rotunda. As Palin and hubby Todd sat autographing books, Olson let fly with the vegetables.

He missed.

If you're going to the festivities, they start at 5 p.m. And you'd better take a look at these rules before you even think about getting a Palin autograph, or posing for a photo.
