Video: GOP candidates get nasty with Iowa caucus just days away

With the crucial Iowa caucus looming, Republican White House hopefuls jockeying for position have taken to intense pushing and shoving.

Mike Huckabee and John McCain are firing back at "aggressively negative" campaign ads from fellow GOP presidential aspirant and former Massachusetts governor Mitt Romney, reports ABC's Jake Tapper.

In one ad, Huckabee is knocked by Romney for his record against crime while governor of Arkansas. Huckabee responds that the people of Iowa are "hearing things about me that I don't like, but they're also hearing things about me that aren't necessarily true."

Meanwhile, McCain is defending himself against criticism from Romney over the Arizona senator's vote against President Bush's tax cuts. "I know something about tailspins," McCain says, "and it's pretty clear Mitt Romney is in one."

Huckabee spoke to reporters after bird hunting in Iowa. "Don't get in my way," he jested while standing over the body of a pheasant he'd just shot. "This is what happens."
