Rove We have heard for months that the Democrats’ election prospects would brighten once they pivot from health care to the economy.

But that seems increasingly unlikely. The reason is simple: President Obama overpromised on his stimulus package and then grossly underdelivered. That has caused public confidence in his ability to handle the economy to drop.

But that hasn’t stopped the administration from spinning.

Take this past Sunday’s media blitz in which White House advisers swarmed the morning talk programs. National Economic Council Director Larry Summers, for one, said on ABC’s “This Week” that the most recent unemployment numbers are “hardly satisfactory,” but nonetheless “good news” because job creation “is running somewhat ahead of what the administration was forecasting.”

That doesn’t square with what administration offi cials said last year. Pass the stimulus and unemployment would be at roughly 7.5 percent by now, they promised.

Instead, unemployment was frozen at 9.7 percent last month, where the Obama administration predicted last year it would be now if nothing were done. Joblessness has neatly followed the pattern of persistent high unemployment the Obama administration said would occur if Congress failed to pass the stimulus package.

Even with last month’s 162,000 net new jobs created, the country is on pace to end the year more than 5 million jobs short of where Obama suggested the country would be with his stimulus.

The stimulus money also hasn’t been spent on the time line the president promised when he signed the bill into law. Recovery. org reports less than 40 percent of the stimulus had been paid out.

Overpromising on the stimulus and then underdelivering has left many Americans skeptical about Obama’s leadership.

A Gallup poll, for example, shows that 61 percent of Americans disapprove of the president’s handling of the economy. That’s up 22 points since about this time last year.

By big margins, Obama- Care is unpopular and Americans distrust the administration’s claims that its new entitlement program is affordable and “won’t add a dime to the deficit.”

It won’t only add a single dime to the deficit; it will add zillions of them. ObamaCare only appears to be affordable on paper because it includes 10 years worth of revenue from huge tax increases and gigantic Medicare cuts to pay for six years of spending.

What’s more, 82 percent of the $434 billion expansion of Medicaid and 84 percent of the $466 billion in subsidies for insurance companies are spent between 2016 and 2019, after Obama would leave office — even if he serves a second term.

When voters consider the true 10-year cost of ObamaCare, many will be fired up to vote against congressional Democrats.
