Pam Dawson is so stupid, I would much prefer to tell her that Palin's travels are coming out of federal stimulus money that was appropriated to the office of the governor of Alaska. When she resigned, the Republicans in Congress added an amendment to the Obamacare bill to allow her to personally keep the money.
Those funds are supplemented by the Koch Brothers Foundation, from money donated by super rich individuals. The multimillionaire and billionaire donors are allowed credits against their income tax for money sent by the Koch brothers to Palin's travel committee, due to a loophole.
Since the super rich have no tax obligation in the first place, the credits are paid to them in checks from the Internal Revenue Service, sort of like an earned income credit for rich Republicans.
If Pam has any more questions, I hope she'll post them at the DUmp, so we can help her out.
