Prestige of the office, so why is Bush so child-ish

Remember how one of the big things about Bush and the Republicans is that they were going to bring back respect for the office of the Presidency? There were going to be adults running things again? I know it's hard to remember that far back (considering it was all BS anyways), but really, does this kind of childish taunting indicate in any way that Republicans are adults:

The president noted that... the Giants vanquished... the Dallas Cowboys. Many Dallas fans pinned their team's surprise playoff loss not on the Giants, but on [Jessica] Simpson... Apparently, Bush bought in.

"I'm a good sport," Bush said at the South Lawn ceremony. "We're going to send Jessica Simpson to the Democrat National Convention."

The Democrat National Convention. If the intent is to show that you have contempt for your political opponents, I guess that works. For people that push that "United We Stand" front, though, using the equivalent of "nanny nanny boo boo" seems a little... disuniting.
