I have an alternate theory: Trump thinks Obama will be a 1 term president. I also don't think talking ill of the dead is ghoulish. I do it, and I think speaking honestly about the dead is more important than "respecting their memory".
trump is right up there with newt. They don't care what the public thinks because they both have enough money to say whatever they want and let the republican voters eat it up. I can't wait for the 2014 voters to finally come to their senses and get rid of the white trash that has been holding back our country for years.
