Well, not explicitly.

However, John McCain does make a telling point here.

“His voting record … is more to the left than the announced socialist in the United States Senate, Bernie Sanders of Vermont.”

McCain is, however, not quite correct. The American Conservative Union gives both Obama and Sanders an 8% rating -- meaning that Obama is not more left-wing than a socialist, merely as left-wing as a socialist. However, I don't think that is anything that Obama wants to brag about.

UPDATE: Ed Morrissey offers a somewhat different take.
