With Obama and Hillary tied up in a battle with one another that could last all the way to the convention, the task of softening up presumptive GOP nominee John McCain has fallen to the Democratic National Committee.

In a preview of further attacks to come, the DNC has released this web video documenting McCain's multiple flip-flops on Iraq...

It's good stuff. But once McCain secures the nomination, which could come any day now, he will obviously begin consolidating the GOP behind him and will get a big jump on the Dems as a general election candidate.

Which means that while we all wait for the Dems to select a nominee, which could take months, the DNC will have its work cut out for it as the only line of defense against the entire McCain/GOP operation.
