UPDATE - 7/15, 7:00 PM: Politico makes a nearly identical argument. Ace tears it to shreads. Details below.
The folks at ABC News are confused. Democrats are passing all this awesome legislation, they posit, so why are Americans acting so hostile and looking to hand Congress to the GOP? The key problems, ABC's Z. Byron Wolf deduces, are that Democrats simply have not embraced liberalism enough and Americans have failed to perceive just how great the Democratic agenda has been.
"The imminent passage of a tough new Wall Street Reform bill," wrote Wolf, pictured right, on ABC's website, "will cap off a wildly productive two years for Democrats in Washington – they will have passed two pieces of sweeping legislation and an enormous $800 billion stimulus bill to deal with the ailing economy."
Wolf goes on to wonder why those three pieces of legislation haven't benefited Democrats' electoral prospects. Let's see: 6% of Americans believe the stimulus bill created jobs, a strong majority favors repealing the health care bill, and almost 80% of Americans polled have little or no confidence that the financial reform bill will achieve its stated objectives. Is Wolf still confused?
