Sen. McCain campaigned in Concord, New Hampshire last week.
WASHINGTON (CNN) - Republican presidential candidate Sen. John McCain is betting heavily on the New Hampshire primary, hoping his muscular approach to national security will appeal to the state's Republican voters.
To win in the New Hampshire primary, McCain needs the support of the Independent voters who helped him win in 2000, many of whom are wary of his support of the Iraq war.
"Most Republicans support the war. Most Independents don't," CNN senior political analyst Bill Schneider said. "Any gains McCain makes with Republicans on the war are likely to be negated by losses among Independents."
If he fails to strike that delicate balance the Arizona Republican may have to cash in his chips and go home in January.
