I nominate this for second-silliest US political ad to make reference to a turtle:
The candidate, Dwayne Stovall, is a Tea Party guy trying to unseat Sen. John Cornyn (R-Tx) in a primary…although the ad seems to be as much about someone and something else.
The holder of the turtle-reference championship, of course, remains the wonderful and bizarre ad by Mike Gravel in 2007 as part of his quixotic campaign for the Presidency.
