You do have a point about Trump and Allred. All that either of them want is money and publicity. At least Trump is up front about that. Allred tries to mask it by putting on a lovey-dovey display with her client, who are just cash registers for her.
This announcement by Trump was comical. Only a minute fraction of people think that Obama didn't complete college (or whatever is alleged by Trump's supporters) and the whole birther movement has moved to the fringes of the republican party. Making a statement like this will hurt the republican ticket more than anything else.
