No, they don't break it down. However, you can see the daily numbers (based on the previous 3 day samples). We'll see if Democrats keep holding strong as they are right now, even if McCain is leading modestly among Independents. But like I said, both Gallup and Rasmussen, and other polls, just have independents all over the place. At the end, they may just break even.
Thus, attracting Democrats is crucial for McCain to win. The key for Obama is holding about 85% of Democrats. If he does, then this election is over. The tone of the convention has been really negative.
If they break even on election day, Obama has probably won the election.
The Dem vote fraud operation is that good, huh? 
Of course! See US Presidential Election, 1960 for more details.
