"The Bush" needs to get out there and talk some more, he could probably get it down around 20%.

NEW YORK (CNN/Money) - President Bush has lost ground in the public relations battle over Social Security since he kicked off a concentrated campaign two months ago to convince Americans the national retirement program needs an immediate overhaul, according to a recent poll.

A CNN/USA Today/Gallup poll conducted Friday to Sunday said 38 percent of Americans feel major changes must be made in Social Security within the next two years. In January, that number was 49 percent.
