Supporters mix it up outside the GOP debate site.

MANCHESTER, New Hampshire (CNN) - Anti-war protesters mixed with supporters of the 10 Republican White House hopefuls Tuesday night outside Sullivan Arena. Competing campaigns and interest groups sought to out-shout one another about two hours before the candidates squared off in the Granite State's first GOP presidential debate.

A banner exclaiming "End the War Now, Bring Our Troops Home ALIVE" was surrounded by signs for former Massachusetts Gov. Mitt Romney and former Arkansas Gov. Mike Huckabee.

The loudest shouts were coming from supporters of Texas Rep. Ron Paul, Arizona Sen. John McCain and Romney.

Other interest groups calling for affordable health care and ending poverty also had a presence. But perhaps the most endearing signs were held by two elementary school age girls that said simply, "I (heart) Huckabee" and "NH (heart) Huckabee."
