Obama ad hits McCain on social security

Another unreleased Obama ad, this one airing in Flint, Michigan, goes after a favorite Democratic issue at an economically scary time: Social Security. (It's not a good week to have had, as so many Americans do, your retirement savings in equities.)

The spot accuses McCain of wanting to privatize the program. The AARP, which opposes such plans, but also follows this closely, has a summary of McCain's past support for diverting some, but not all, payroll taxes into private accounts.

These unreleased spots raising alarms about bread-and-butter economic issues may say more about the real race than does the cable news buzz.
