Fred's first ad

From NBC's Kelly O'Donnell
Fred Thompson will be up with two 30-second TV spots starting tomorrow. Even though the 6-foot-5-inch Thompson will be a no-show at tomorrow's Republican debate in New Hampshire, he will cast his tall shadow on the event. One of the ads will run during commercial breaks. The ads, entitled "Debate" and "I'm in," will be widely released tomorrow.

On Thursday, the similar spot "I'm in" will run "all day" on FOX News Channel, according to advisors. The difference between the spots boils down to a time reference, noting before and after Thompson actually declares.

Thompson jumps into the race with a Web announcement, which was taped at his McLean, Va., home on Saturday. It runs 15 minutes and, according to advisors, outlines his rationale for running.
