If the purpose of Al Gore's movie "An Inconvenient Truth" was to ready himself for another presidential run, it doesn't seem to have helped his poll numbers.
A Gallup Poll shows that former U.S. Vice President Al Gore's documentary on global warming has had little effect on his popularity with voters.
The poll was taken between June 23-25, a month after the release of "An Inconvenient Truth," which showed surprising strength at the box office, especially immediately after its release.
Gallup found that 48 percent of those polled had a favorable opinion of Gore, while 45 percent had an unfavorable one. His favorable ratings were about the same as they were in 2002 and 2003 -- and below those during most of the time he was vice president and campaigning for the presidency.
Gore was far more popular with Democrats and non-white voters than with Republicans and white voters, and more popular with younger voters than with those 65 and older. Independents were almost evenly split with 47 percent viewing him favorably and 46 percent unfavorably.
