GDANSK, Poland (AP) -- An Obama campaign official said Mitt Romney's overseas trip isn't demonstrating any diplomatic skills.
But Republicans said the controversies that followed Romney on his first two stops -- in London and Jerusalem -- won't linger.
After offending some Britons by suggesting that they weren't ready to hold the Olympics, Romney angered Palestinians by telling Jewish donors that cultural differences helped make them more economically successful than the Palestinians are.
Obama senior strategist David Axelrod tweeted, "Is there anything about Romney's Rolling Ruckus that would inspire confidence in his ability to lead U.S. foreign policy?"
But a senior aide to former Republican rival Rick Santorum, Hogan Gidley, said he doubts that Romney will suffer any long-term effects among voters who are still undecided three months before the election.
Romney is now in Poland, the last stop on his trip.
