Bush's margin since Nov 3 has dropped from 3.05% over Kerry to 2.69%. It looks like my prediction that the margin will drop at the end to 2.6% looks about right. Hopefully, it will stay above 2.5%, so the rounding is up to a 3% margin, rather than down to a 2% margin.
"Bush's margin since Nov 3 has dropped from 3.05% over Kerry to 2.69%"
Pres. Bush's reduced margin over Kerry is mainly due to CA where Kerry has increased his lead over Bush by more than 200,000 votes since election day.
