Iowa's premier political news site: http://www.iowapolitics.com Republican presidential candidate Mike Huckabee said Dec. 31 he intended to air ads that respond to negative attacks made by GOP rival Mitt Romney. The Monday press conference was intended to address those ads. However, 10 minutes prior to taking the stage, Huckabee announced his campaign was pulling the ads from the rotation. The former Arkansas governor said he would not go negative because he has to live with himself after the caucus.
