The White House is counter-attacking in hopes of gaining the upper hand in the battle over Social Security. A national poll finds support for President Bush's Social Security plan falling, and congressional Democrats are virtually unanimous in their opposition to Bush's plans. Fighting back against the ad campaigns of opponents, President Bush and top aides plan to barnstorm the country, making 60 stops over 60 days.

And he's welcoming Fed chief Alan Greenspan's warning yesterday that a Social Security fix can't wait. Without changes, the Social Security trustees project that by 2042, the program won't have enough to pay promised benefits fully.
