I think it’s a difficult situation and that they have to keep up appearances. Obama is not going to run again, but I suspect his wife might, or if not Moochelle, somebody related to them. So he doesn’t want the hatred to be too obvious because they might want funding from the Clinton machine.
The current Dem prospects are dismal because Clinton and Obama wouldn’t permit any new political forces. The GOP has a ton of good candidates (Cruz, Jindal, Rubio, Fiorina and, of course, the not-so-good GOPe candidates such as Bush) because there are still young people involved in conservative causes and they have been rising from the ranks. Under Obama, there was nobody, and even the black radicals around him are elderly.
That brings up a new set of questions: Just how much has Bill & Hill collected already on the basis that Hill can deliver once sworn in? Also, how much of a shortfall in income will her not being elected cause the Clinton crime machine???
