DES MOINES, Iowa - Today there will be one last push for the presidential candidates before Thursday's Iowa caucuses.
Democrats Barack Obama and Hillary Clinton will have two-minute ads broadcast around the state this evening.
John McCain will be back in Iowa today after adding campaign stops in the Hawkeye state hoping to build on new momentum.
A Des Moines register poll places McCain 3rd behind frontrunner Mike Huckabee, and Mitt Romney once considered the favorite.
Later today Republican Mike Huckabee will leave Iowa to travel to California to appear on NBC's tonight show with Jay Leno, but he'll be back in time for more campaigning tomorrow.
