(CNN) - The same day a new poll showed the presidential race in a dead heat across three major battleground states, President Barack Obama's top campaign adviser remained confident that the numbers will line up for the president in November.
"I like our math in terms of getting to that 270, but we're going to have to fight hard," David Axelrod said Thursday, referring to the number of electoral votes needed to win the election.

In his comments, which came in an interview to air on CNN's "John King, USA," Axelrod downplayed the tightness of the race in key swing states. Obama and Romney are neck-and-neck in Iowa, Colorado and Nevada, according to new polls released by NBC News/Marist on Thursday.
"What's happening is, in my view, absolutely predictable. We knew this would be a close race. They're called battleground states for a reason," he said. "They're going to be close throughout."
CNN Chief National Correspondent John King outlined his electoral analysis in the interview, saying he expects Obama currently stands at 247 votes, with Romney at 206, leaving six or seven states as toss-ups.
Largely agreeing with that assessment, Axelrod said he expects more states will lean toward Obama, though he didn't name the exact states he had in mind.
Pointing to an example of the campaign's readiness for a swing state fight, Axelrod mentioned the $25 million ad buy purchased by Team Obama this month across a dozen battlegrounds.
In 2008, Obama won the presidential election with 365 electoral votes, or 53% of the vote, over Republican Sen. John McCain.
While the president carried several key states last time around–Virginia, Wisconsin, Iowa, Florida–those states made big Republican gains in elected offices in 2009 and 2010, making this cycle a tougher fight for Democrats.
