"It's official, Arnold said he will enter the race for governor. At least that's what everybody thinks he said"

This quote by David Letterman is referring to Arnold Schwarzenegger's statement that he will be running for governor of California. It is an amusing take on the circumstance, as Letterman suggests that Arnold's declaration was not totally clear. This might be interpreted as a jab at Arnold's accent, as he is initially from Austria. It might likewise be interpreted as a joke about the media's propensity to misinterpret statements, as the quote implies that the general public is not completely sure what Arnold said. In any case, it is clear that Arnold has actually made his objectives understood and that he will be running for governor.
