I never liked Nancy Reagan; but it's pretty classless to mock a frail, elderly woman. (Note he was not kind in his revelation about his own "typical white person" grandmother, either.)
It's even worse to mock the widow of a great former president. Whatever you think of her, she deserves respect.
Especially classless was mocking Nancy Reagan on stage, before hundreds of reporters and television cameras, knowing the "joke" would be heard by millions. This wasn't some private remark that got picked up by a live mike.
(Less important, but on a factual note: I never heard anything about Nancy Reagan holding "seances." Did Obama, like his gaffe-o-matic VP, get his history mixed up? Perhaps he was thinking of Mary Lincoln? It is true that a disgruntled Reagan ex-staffer, who wrote a tell-all memoir, stuck the knife into Nancy by alleging that she began consulting an "astrologer" after the attempted assassination of her husband. Superstitious, yes; but not quite the same thing as "holding seances.")
So Hussein can lie like this,,,and does the Press call him on it?
