I don't see anything on the recent diaries about this, so here's some good news:
NBC/Wall Street Journal's monthly national poll is in, and the numbers are good:
1,004 registered voters surveyed, MoE +/- 3.1%
Likely voters (September)
Bush/Cheney 48 (50)
Kerry/Edwards 48 (46)
Registered voters (September)
Bush/Cheney 48 (48)
Kerry/Edwards 46 (45)
There's some other good stuff in the internals. Key stats: 33% said the debates make them more likely to vote for Kerry, only 18% more likely to vote for Bush. Also, the attitude about Iraq has taken a staggering 21-point swing towards optimism. It's hard to see how Bush could be competitive without this advantage... let's hope Kerry keeps the pressure on and doesn't let him dodge responsibility for his mistake.
