WASHINGTON — When a virulent disease is ravaging you like a cancer, you don't want a cacophony of voices promoting different or contradictory cures. Yet that is what we're starting to hear about the economic crisis, not only from a politically divided — and pretty scared — capital, but from within the Obama administration itself.

In just the past few days, Vice President Joe Biden has said the young administration misread the depth of the recession — an honest account, since most private economists did, as well. Laura Tyson, an outside economic adviser to the White House, said it's wise to start preparing another stimulus package.

Then President Barack Obama made everything perfectly muddy when he said in an ABC News interview that the seriousness of the downturn and how to attack it is "something we wrestle with constantly." Yet in the next breath, he expressed concern about the burgeoning deficit.

But if anyone's looking for some clear voices, there are 650,000 of them just waiting to be heard. That is roughly the number of long-term unemployed who will begin losing their jobless benefits in September, according to the National Employment Law Project.

Remember, the recession didn't start last fall when the government bailed out AIG and the financial system froze. It began in December 2007 — and 6.5 million jobs have been lost since then. Depending on which state and the sort of triggers that apply to benefits, hundreds of thousands of workers laid off early in the downturn are soon to be left without the basic sustenance of an unemployment check.

Meanwhile, the Labor Department says, the number of unemployed people out of work for 27 weeks or longer continues to grow, reaching 4.4 million last month. In June, three out of 10 jobless workers had been out of work for at least six months, according to the department's data.

The stimulus package the president signed soon after taking office did provide extended benefits and boosted weekly payments. But even that extension runs out on Dec. 26 and would not apply to all the unemployed. Does anyone really believe that a significant portion of the unemployed will have found new work by then? Hardly. Both private and government economists now predict that unemployment will continue to rise at least through the end of this year.

"We can't ignore this moment when all these folks are running out (of benefits)," says Maurice Emsellem of the National Employment Law Project. "That needs to be a top priority, to help these workers."
