(CNN) – Mitt Romney provided a moment of political humor Saturday, regarding the possible entrance of another competitor to the race for the GOP presidential nomination.
"It looks like there is a Senator from Tennessee that you may have heard of that may be coming in late, but not one person in this room is going to vote for Senator Al Gore I promise." Romney's quip was met with laughter before a lunch time audience in Cedar Rapids, Iowa.
Former Tennessee Senator, and actor Fred Thompson's possible entrance into the race has been the subject of recent speculation. He has established a presidential exploratory committee, and is widely expected to join the race later this summer. Thompson, a Republican, was elected to his senate seat, after Gore stepped down to become vice president under Bill Clinton.
Romney is the former Republican governor of Massachusetts. He and his wife Ann, are campaigning in Iowa on Saturday and Sunday.
