If March 2 was "Super Tuesday" in the United States, then Massachusetts Sen. John Kerry is "Superman." Mr. Kerry wrapped up the Democratic Party nomination for president Tuesday, capping a remarkable comeback and -- more remarkable still -- managed not to divide his party in the process. Mr. Kerry can now focus on his rival, President George W. Bush.

Mr. Kerry will need every advantage he can muster. He faces a wartime president with high popularity ratings, who presides over a recovering economy and, perhaps most important, already has a war chest that tops $100 million.

Every four years, the first Tuesday in March in the U.S. is known as Super Tuesday. It is so named because that day hosts the largest number of primaries to select delegates to the Democratic convention. This year the convention will meet in Boston in July to nominate the party's presidential candidate. The individual with the most delegates gets the nomination.
