All the Republican numbers are lower and Democrat higher when they narrow to likely voters (in this poll). Might be a bad sample, might be unenthused Republicans saying they aren't likely to vote. I'm not sure what to think of it.
That's what the Gallup poll shows too. The Dems are motivated and alot of Pubbies aren't. It shows you what anger does. Apparently Republicans aren't all that angered by the attacks on Bush - or maybe they believe them.
