I believe the latest results came from Colorado. Colorado tightened up a lot, check out the results now, Bush only carried the state by 4%. CO does look to be trending to the Dems.
Colorado didn't tighted up much in raw votes. After election night, Bush led by ~107,500 and now his lead is ~99,500 votes. As noted by MODU, this does decrease the marginal percentage.
What is noteworthy is that Bush's nationwide lead has shrunken from 3.5 million to 3,263,499. So his lead has narrowed by ~250,000. Kerry has not gained as much as the 400,000+ votes that Gore did after the initial count was in but, I agree with zorkpolitics that it is mostly because of huge volumes of absentee ballots--mostly from California and Washington. In CA alone, the Kerry lead grew from about 1 million on election night to 1.25 million today. Personally, I maintain that provisional ballots will break close to 51 to 48% in Bush's favor nationwide. I could be wrong, but I think voters on either side were liable to have lapsed registrations or have moved and been required to cast a provisional ballot.
I envision that as midwestern states release their final certified totals in the next two weeks, Bush's margin will grow just a little.
