The GOP clearly doesn't really believe that the Social Security system will be in crisis by 2008 - those who think that matters, though, are mere members of the reality based community. That which serves the Party is true.
The New York Times: Party leaders and White House officials who gathered at the Greenbrier resort also discussed a new rhetorical twist in their campaign to remake Social Security. In meetings on Friday, Treasury Secretary John W. Snow and Representative Bill Thomas of California, chairman of the House Ways and Means Committee, discussed redirecting public attention on 2008 as an imminent danger point for the Social Security trust fund because baby boomers will begin retiring, people present said. Even the most dire analyses say the fund will remain solvent for a decade or longer after that.
