Retired Army general Wesley Clark has repeated his pledge to announce by the end of next week whether he will seek the Democratic nomination for president. The news came yesterday as Clark`s supporters rallied in more than a dozen Arkansas cities. The Little Rock resident is being urged to run by groups that have formed across the country, saying Clark would make a candidate who could beat President Bush in November. Last night, Clark addressed supporters in a speech relayed via the Internet. Second District Congressman Vic Snyder was in the crowd at a downtown Little Rock restaurant waiting to hear Clark`s recorded message. Snyder says that if Clark runs,he`ll support him. Clark, a Rhodes scholar who graduated first in his class at West Point, served as NATO commander during the 1999 campaign in Kosovo. He grew up in Little Rock.
