Rasmussen: Obama Approval Index at 0

Today's Rasmussen poll has Obama's Approval Index at zero. What's especially significant is that this comes four days after ABC's all-day-culminating-with-a-broadcast-from-the-White House health-care plan telethon and five days after a press conference -- one in which, incidentally, some reporters were (finally!) actually asking challenging questions and reacting to the (il)logic of his answers.  Note that, during that time Obama's A.I. never exceeded +2, compared to previous peaks of +10 after the Sotomayor nomination and +9 after his Cairo speech.

In other words, Obama's ability to pump up the numbers via media extravaganzas has hit the point of diminishing returns.
