On Tuesday, President Mahmoud Ahmadinejad of Iran told reporters during a trip to New Delhi, the Indian capital, that he believed that neither Mrs. Clinton nor Senator Barack Obama, the other Democratic presidential candidate, had a chance of winning the election.

“Do you think a black candidate would be allowed to be president in the U.S.?” he asked, the semiofficial Mehr News Agency reported. “We don’t think Mr. Obama will be allowed to become the U.S. president.”

Referring to Mrs. Clinton, he said, “Presidency of a woman in a country that boasts its gunmanship is unlikely.”
