Jon Stewart, Democratic mouthpiece

What media-savvy Democrats perfectly understand is that Viacom’s comedy darlings do a better job conveying liberal talking points than Harry Reid, Mrs. Pelosi, Keith Olbermann and Chris Matthews combined. And Republicans aren’t organized enough to play defense and not smart enough to go on the offense like the left does against Rush Limbaugh, Bill O’Reilly, Mr. Hannity, et al.

So, unchastened, Mr. Stewart has decided to take his partisanship to new heights. Most notably, he is working harder than ever to ensure that elected Democrats escape scrutiny for the financial crisis…

But Mr. Stewart is now actively fighting for an administration and a party he believes in. He is treading lightly with Barney Frank. Chris Dodd may become a fall guy, but only if it serves the master’s needs. And the Republicans are public enemy number one.
