Post Debate Polls Show Obama's Lead Growing

I was just reading a story concerning last weeks Presidential debate at Yahoo News, and
found this analysis of poll data at Politico:

Two days after a presidential debate many commentators scored as a tie, it's beginning
to look like the public saw things differently, as several polls show a small but significant
post-debate boost for Barack Obama.


A USA Today/Gallup poll released Sunday showed 46 percent of debate-watchers believed
Obama outperformed John McCain, while.just 34 percent said McCain got the better of the
exchange. Thirty percent of debate-watchers said they had a more favorable opinion of
Obama following the debate, compared with just 14 percent who said their opinion of him
had worsened. Respondents whose opinion of McCain changed as a result of the debate were
evenly split, as 21 percent said their view of McCain had improved because of it and 21 percent
said it had worsened.


The poll surveyed 701 adults who watched Friday's debate, and all interviews were conducted
on Saturday.


Obama's numbers have ticked up nationally since the debate, the first of three scheduled this
year, along with next Thursday's vice-presidential face-off In the Sunday update to Gallup's daily
tracking poll, Obama widened his lead over McCain to 50-42 percent. Friday, in polling that
preceded the debate, Obama had a five-point, 49-44 percent advantage.
