Romney campaign senior adviser Ed Gillespie said that, with two days left in the campaign, the "map has expanded" for the Republican nominee.
Gillespie argued that Mitt Romney has been able to secure leads in Florida, Ohio and Virginia, despite polls showing Obama ahead in some of those states, while also making new efforts to win in Pennsylvania, Michigan and Minnesota.
"When you look at where this map has gone, it reflects the change and the direction and the momentum toward Gov. Romney," Gillespie said on ABC's This Week. "And the fact is that a state like Pennsylvania being in play, a poll out today showing Michigan a dead heat "¦ the map has expanded."
Gillespie dismissed the Obama's campaign's claim that they have a stronger ground than the Romney campaign has. "Number one, their ground game is not superior," he said. "And, number two, I think those undecided voters are going to turn out, and they're going to break pretty strongly against the president."
With just days before the election, Gillespie said Obama's sub-50-percent position in some polls should be disconcerting for the president.
"When you're the incumbent president of the United States and you are at 47 percent or 48 percent on your ballot two days before the election, you are in deep trouble," Gillespie said. "And that's where they are today."
