Sen. Hillary Clinton's presidential campaign site offers the following equation over a photo of the New York Democrat: "Strength + experience = change."

"The reason for Hillary's growing support is that voters want change, and they know that only Hillary has the record of fighting for the kind of change they want, and the experience to execute it," Clinton strategist Mark Penn wrote in a campaign memo this morning.

The memo outlines the former first lady's strong position in nearly all polls done at the national and state level.
