Clinton said she feels 'lucky' to give Rove 'heartburn.'
WASHINGTON (CNN) – Senior White House aide Karl Rove has stepped up his attacks against Democratic presidential frontrunner Hillary Clinton, and the New York Democrat said she couldn't be happier.
“I feel so lucky that I am now giving them such heartburn,” Clinton said Wednesday while campaigning in Iowa.
Clinton was referring to Rove's recent assertion on Rush Limbaugh's radio show that the New York senator was "fatally flawed," and would lose a general election match up because her negative favorability ratings are too high.
"She is going into the general election, depending on what poll you look at, with high 40s on the negative side and just below that on the positive side. There is nobody who has ever won the presidency who has started out in that position," said Rove, who is often referred to as "Bush's brain".
Clinton's campaign spokesman Phil Singer quickly took the opportunity to link Rove - one of the left's most despised figures - with Illinois Sen. Barack Obama.
"It sounds like Karl Rove is writing Sen. Obama's talking points," Singer told CNN.
Obama has repeatedly made the argument he can unite the country better the Clinton can. He told the Washington Post Tuesday, "I think it is fair to say that I believe I can bring the country together more effectively than [Clinton] can."
UPDATE: Responding to the Clinton campaign's comments, Obama spokesman Bill Burton tells CNN, "I just don’t think voters are looking for four more years of scorched earth politics from their White House."
