Romney didn't start the story, but there he was back in May passing it on to a gathering of potential donors (presumably rich people, but maybe not) with every Hannity element of the story intact ~ right parts, wrong parts, unrelated parts ~ and bizarre parts, then it was combined with something (Now retired) G. Gordon Liddy got into back in the Clinton days ~ the old "Oh, you 43%" ~ a reference to Clinton voters.
Most likely he listened to Liddy as well ~ as did I. But Obama didn't actually run for office at that time.
It's entirely possible it's one of Romney's staffers sticking all that stuff together, but least she could have done was stick it together in the right order, the right nuance, and the right representation of relationship to the rest of the statement.
Now, about rich donors being surprised by stories taken from Sean Hannity's show ~ and melded with G. Gordon Liddy aphorisms, that's a clue on how to get rich ~ don't listen to talk radio!
Talk radio would do you a great deal of good.
You might become informed.
