The Ronald Reagan seance comment was stupid. I cringed. Obama called Nancy Reagan to apologize. I think the conservatives have had enough of nitpicking so aside from some remarks about it they will let it slide.
Obama's going to need to think more on his feet and not get too comfortable/cocky. He talks slow enough and does enough "uh...."s to be thinking about what he says. Leave the off-hand jokes in your head, Obama. Now we need more substance and less talking.
