Greg Sargent is smart, and says interesting things:
The Horse's Mouth: As pollster Andrew Kohut explains to the paper, there's a very interesting dynamic at play right now which is swamping the GOP's hopes for recovery. The GOP is a victim of its own success: Because the party has been successful at conflating Iraq and the war on terror, Kohut says, its efforts to talk about terrorism now are failing because they're getting overshadowed by the public's far more pressing concerns about the Iraq war. So the more Republicans talk about "terror," the more people are reminded of the disaster they've created for us in Iraq.
In a way, it's like the political equivalent of quicksand: The more the Republicans thrash around to extricate themselves from this morass, the deeper into it they sink.
