(CNN) - As the candidates try to win over undecided voters, both Republicans and Democrats are pushing a message of change.
CNN's latest "poll of polls" shows Sen. John McCain leading Sen. Barack Obama 47 percent to 46 percent.
Monday's poll of polls shows that 7 percent of voters are undecided - enough to push either candidate over the top.
With the election less than two months away, the candidates have limited time to sway undecided voters who hold the election in their hands.
According to John Avlon, author of "Independent Nation: How Centrists Can Change American Politics," independent and swing voters are looking for a break from the Bush administration.
"What they're looking for in this campaign is a candidate who's going to end the hyper-partisanship in Washington and who's going to have credibility on reducing spending, but also sort of the antidote to the Bush administration," he said on CNN's "American Morning." "They've been - instead of fiscally conservative - fiscally liberal and socially conservative, and that's the opposite of what independents and swing voters want."
Change essentially means new people and new policies, said Bill Schneider, CNN's senior political analyst.
"It's exactly the theme that people want for this year after eight years of the Bush administration," he said. "But the big puzzle in this election is - what's the best way to get that?"
