This is the first add from Progressive Media, the David Brock-helmed independent expenditure group that's supposed to whack John McCain while Clinton and Obama continue to duke it out:



When you think about how potentially damaging something as basic as "John McCain agrees with George W. Bush about important issues" could be as an attack, it's a stark reminder of how bad the fundamentals are for the Republicans. I would, however, somewhat prefer to see early attacks focus on McCain's disastrous thinking on national security issues -- the economy argument is very easy to make, so it's more important to get started on the more difficult task of making the case that for all the honor of McCain's military service, it's left him with a reckless and absurd strategic vision.
