An Associated Press-GfK poll released Wednesday showed Obama surging to a seven-point lead, 48-41, over McCain one month before the presidential election. Three weeks ago, McCain had a slight edge over Obama in the AP-GfK survey.
Other surveys also showed Obama ahead of McCain nationally and beating him in several swing states, including Ohio, Florida, Pennsylvania and Iowa.
"Look, we're doing fine," McCain told Fox News. "We were up in the polls, and then we were down in the polls, and we were up in the polls, and down in the polls ... you know, we can't worry about the day-to-day tick-tock."
McCain added: "I think we're doing fine. We've got a lot of work to do. I always love being the underdog, and I think we're going to be up late on election night. But I'm very happy with where we are."
