White House press secretary Dana Perino said Monday the incumbent's invisibility is by design because "the Republican Party wanted to make this election about John McCain."
The president knows there are people in this country who want change and are looking for something new, Perino said.
"We're realistic about the political environment that we are in," she said. "What keeps him going is knowing that he's done the right thing."
