“Too little, too late” says the Washington Post:

The candidate was outraged – just outraged – at the country’s sorry fiscal state.
“We have managed to acquire $13 trillion of debt on our balance sheet,” he fumed to a roomful of voters. “In my view, we have nothing to show for it.”
And that was a Democrat, Sen. Michael Bennet of Colorado, who voted “yes” on the stimulus, the health-care overhaul, increased education funding and other costly bills Congress approved under his party’s control.
Faced with a potential wipeout in November’s midterm elections, candidates such as Bennet are embracing budget cuts with the enthusiasm of Reagan Republicans.

Though Bennet has been campaigning on his own version of fiscal austerity–touting his plans as a deficit hawk–it was the “nothing to show for it” comment that drew national attention.

Bennet went on to say he felt that “it’s immoral to leave this to our children” and implicated himself, his party, and President Barack Obama in sharing the blame with the previous administration.

But it is not budget and spending cuts that the Democrats hope will return them to favor with the electorate. They are pegging their hopes on increasing taxes by allowing President George W. Bush’s decade-old tax cuts to expire at the end of the year.

Others aren’t so sanguine about the prospect of newly-found Democratic self-discipline:

Bennett [sic] hopes to capture these voters with his stern lectures on the budget. Seth Masket, a political science professor at the University of Denver, is not sure he can.
“It will be tough for him to paint himself as a deficit hawk,” Masket said. “He’s very visible as someone who is closely allied with President Obama.”
