Among Democrats, Sen. Hillary Rodham Clinton of New York leads with 38 percent, followed by Sen. Barack Obama of Illinois at 21 percent. Former Vice President Al Gore is at 14 percent and 2004 vice presidential nominee John Edwards is at 10 percent. The rest of the field is in single digits.

Clinton leads Obama among voters who mention honesty and strong character, compassion, intelligence and stance on issues. The former first lady is tied with Obama among the small number of respondents who value experience, a surprise given Obama's short stint in Washington.

Policies may not get candidates elected. But politicians can use their policies to connect with voters at a gut level.

Former President Clinton's book-length economic blueprint showed voters he would work hard to tackle problems they cared about. His empathy was a winning trait in 1992.

Bush won re-election in 2004 when most people were opposed to the war in Iraq. He used the against-the-grain war policy to cast himself as a strong, decisive leader. It worked until voters started doubting his honesty and competence in 2005.
