The Iowa caucuses and New Hampshire primaries are less than three weeks away, and the race for presidential nomination is dominating the air ways. It's difficult to project who could be elected. The GOP field lacks a clear frontrunner. The Democrats remain a close three-way race. Sen. John McCain may be a beneficiary of the fight between Mike Huckabee and Mitt Romney. Likewise, John Edwards may benefit from the bout between Sen. Hillary Clinton and Sen. Barack Obama.
