WASHINGTON (CNN) - With Thanksgiving falling exactly six weeks before the lead-off Iowa caucuses, the presidential candidates can’t afford to take this holiday week off.
Democrats Hillary Clinton, Barack Obama and John Edwards all swing through Iowa, the most competitive early battleground. Polls suggest it's still a three-way contest there .. unlike other states where Clinton is the undisputed leader.
Second-tier democratic candidate Joe Biden apparently hopes to make some headway in Iowa. He’s camped out there all week, including Thanksgiving Day.
On the Republican side, Iowa front-runner Mitt Romney spends part of this week in the Hawkeye state. New polling shows underdog Mike Huckabee may be closing in on Romney's lead there. Even Fred Thompson plans a relatively rare swing through Iowa. But national front-runner Rudy Giuliani sets his sites on other battlegrounds this week, including Florida. It’s another sign that he’s looking beyond Iowa and New Hampshire and counting on wins in later contests.
