Treasury Secretary John Snow (search) acknowledged Wednesday that the Bush administration has not yet succeeded in selling its plan for Social Security (search) to the American people, and said backers would continue to travel the country educating people about the program's problems.

Supporters in Congress, armed with GOP-prepared materials, are holding meetings with constituents all over the country this week to try and build support. Wavering members of Congress are holding similar meetings to gauge public opinion.

Snow is traveling this week to Florida to campaign for the Bush plan.

He said Wednesday that he understands that Congress has been leery about creating personal accounts as part of Social Security, as Bush has proposed.

"We still have some work to do," Snow said.
