This guy thinks it's ironic that Bush is pushing Social Security reform so hard, and I admit he makes a good point:

As it turns out, the voters who will benefit most if the Bush Administration creates private accounts are many of the same voters who formed the core of Democratic presidential candidate John Kerry’s support during the 2004 election.

...

If you’re a 21-year-old entering the workforce this year, and you’d like to retire at age 65, projections show Social Security – on its current course – going broke several years before you retire. If this turns out to be the case, you’d be spending most of your working career paying for other people’s benefits. Clearly, the benefits of reforming Social Security will flow most directly to younger workers, because they have the most to lose under the current system.

However, the irony here is that younger voters are the only age demographic that went strongly against President Bush in the 2004 election. According to exit polling of 2004 presidential voters, Kerry won the 18 to 29 age bracket by a roughly nine-point margin. Bush, on the other hand, found his strongest support among older voters, running up a 10-point margin in the over-60 age bracket.
