Words Obama can't use

From Ace of Spades:
Words Obama can't use: Success, growth, prosperity, plunging unemployment, factory openings, fury of new-home starts, expanding investment,growing middle class, increasing wages, security.
Why did Reagan, and then Bill Clinton, connect with people? It wasn't all about charm. It was also the content of their communications. Reagan could speak of it being Morning in America Again, because it was. Clinton could speak of 4% unemployment, because he had that (briefly).
They could talk about how great people had it.
Obama? He can only tell you that in four years time, his doctrine says things should be getting better.
