Celebrities have dinners for the same reason both Dem. & Rep. leaders have $25,000.00 a plate dinners - to raise money! SJP certainly won't be inviting the guy off the street corner to attend; she'll invite her other monied star friends to come and rub elbows with the Prez. All about the $$.

SIDE NOTE: I find all of these campaigns absolutely embarrassing to the outside world, as well as to the average Joe who's trying to make ends meet.
