[Q]: (CNN) -- Former Bush adviser Karl Rove said Sunday that Sen. John McCain had gone "one step too far" in some of his recent ads attacking Sen. Barack Obama. Karl Rove said both candidates are guilty of going too far in their attacks. Rove has leveled similar criticism against Obama. "McCain has gone in some of his ads -- similarly gone one step too far," he told Fox News, "and sort of attributing to Obama things that are, you know, beyond the '100 percent truth' test."
