CHARLOTTE, N.C. - Fresh from her Democratic National Convention speech Tuesday night, first lady Michelle Obama has returned to fundraising for her hubby's campaign with a new approach: Diet for Barack.

In her latest email pitch, she compliments a donor who turned over the family pizza money to the campaign. For the health-conscious first lady, its a two-fer: families can take a break from fatty pizza and help the reelection.

Friend --

I know your life is full -- with work, or school, or family -- and yet you still find the time to help out when you can.

You may have a tight budget, but you give what you can afford.

A woman recently told the campaign her family skipped a pizza dinner at their favorite place so that they could make a difference in this election.
