Does he want to lose reelection? You'd expect him to be running away from Bush now, not making lame defense and apologies for him.
That's the difference between the Democrats and the Republicans. The Republicans know to toe the line. Rep. King (NY-03) says some pretty crazy sh**t too. Reynolds (NY-26) is quite obnoxious too. These are all in competitive districts, but they have a spine anyways. Meanwhile, we're stuck with at best uninspiring moderates at worst backstabbers in many of our marginal (and even not marginal) districts.
The fact is the Republican strategy is a winner, and it's only because of a huge shift in the national mood against their pathetic leadership that they might lose Congress.
