clinton's expense but it was a line he prepared and memorized. ben carson was organic. trump, the rosie o'donnell line was organic. you may not like the joke but that was a funny moment. >> it also wasn't true. it might have been funny but it wasn't true. >> it was funny for the audience. ronald reagan and many presidents before president obama used jokes much more self-deprecating manner to make you likable. obama has weaponized humor and i've written about that for cnn and the daily beast. you have trump taking it to new levels. he tweeted after the debate mocking megyn kelly on twitter and fox news. it makes you go "oh, my god i can't believe this is happening" and he's still doing fine in the poll polls. >> i was on a radio show in birmingham, alabama and i asked what was up and they said they liked trump and ted cruz and i said was there any bash lash and they said yes, they didn't like fox. i said -- >> well, that's interesting. >> yes. exactly.
