Washington  - The Republican Party released a new television advertisement Tuesday that mocks Germany's adulation with Democratic presidential candidate Barack Obama during his visit to Berlin last week.

The one-minute video contains interviews with some of the 200,000 people who attended Obama's speech in Berlin Thursday, suggesting his "international fan base" is unfit to judge who is best suited to be US president.

The ad makes fun of Germany's musical tastes, its love of US television star David Hasselhoff - who succeeded as a musician in Germany but failed in the United States - and its leftist leanings.

"I have friends in America who are Marxists, and they support, are working for Obama," says one supposedly admiring fan of Obama in Berlin who appears in the ad. Another compares Obama to Cuban revolutionary Che Guevara.

Obama returned Sunday from a week-long trip to Europe and the Middle East in an effort to boost his foreign policy credentials. Republican rival John McCain derided Obama's overseas visit as a "premature victory lap." (dpa)
