Democratic presidential candidate Wesley Clark plans to spend the day again today in New Hampshire, trying to close the lead that former Vermont Governor Howard Dean is showing in the polls. Recent polls show Clark has passed Senator John Kerry and has moved into second place. The tightening of the New Hampshire race has prompted Dean to revise his strategy and is injecting new energy into the retired Army general`s campaign. Clark is not competing in the kickoff Iowa caucuses on January 19th and instead is focusing much of his energy and attention on New Hampshire`s January 27th primary. Private polling by two campaigns in New Hampshire showed that Dean`s lead has shrunk to single digits from a first-of-the-year high of about 25 percentage points. That`s according to officials familiar with the polls. Dean is locked in a close four-way fight in Iowa. Dean spent yesterday in Vermont and planned a campaign stop in New Hampshire before heading back to Iowa.
