Clinton campaign pollster and strategist Mark Penn.
(Before her January 2007 debut as a candidate, the senator’s team wrangled over how to portray her. Some advisers wanted to emphasize her soft, human, and witty side, and to cast her as an agent of change. Penn argued, conversely, that she needed to appear tough as nails, emphasize her experience in Washington, and refuse to acknowledge any misteps in past judgement, such as her vote on the Iraq War. Penn won the internal debate, and the rest is history.)
