I've been wanting to make this point for awhile, but never got around to it.
Obama reminds me of the character played by Charles Grodin in the original version of The Heartbreak Kid back in the early 1970s. At the end of the movie, when he's finally married the shiksa goddess played by Cybill Shepherd, he's at their wedding reception and the scene starts off with him telling a group of adults what he wants to do with his life. He wants to "help people," or words to that effect, typical content-free, skills-free liberal do-gooderism. Over the course of the wedding reception (this is the final scene of the movie), he keeps repeating this mantra to gradually descending groups of people, until, at the end of the movie, he's telling his story of wanting to "help people" to a group of children, with the implication that they are the only ones left who'll take him seriously. Meanwhile, Shepherd and her father look at him with the dawning realization that he's a schlub. It's an absolutely killer scene in a movie that was much much better than the later, Ben Stiller version.
Here's another killer scene between Grodin and a menacing Eddie Albert as Shepherd's father, after the first time that she brings him home to meet the family:
Anyway, that's what Obama reminds me of.... a guy whose bullshit can no longer hold the attention of serious adults, a guy we now all see through.
