"Huge Drop in Popularity: Voters souring on McCain, Obama stays steady"
"McCain to Letterman 'I Screwed Up.'"
Yahoo has shown itself an incredibly biased news source during this election cycle.
Obama is leading, but according to the polls quoted above - there has been no significant change over the last few months - and the margin of error for these polls still gives McCain a shot.
I have switched to Google - too bad I still have Yahoo.mail.
