As most of us worry about unemployment and real issues confronting us, health-care is being debated this morning on Capitol Hill in a rare Saturday session. The Democrats have almost a mania to pass this unpopular bill. Wall Street Journal columnist John Fund explains the strange phenomenon:

But buried in the surveys is an explanation for the Democratic obsession to pass the bill: An overwhelming 76% of Democrats back it. “They believe the liberal base expects them to deliver and will punish them if they don’t,” says Democratic pollster Doug Schoen, who worked for Bill Clinton in the 1990s.

That fear is backed up by a new poll taken for the Daily Kos, the left-wing Web site: 81% of self-described Republicans say they are certain or likely to vote in 2010 compared to 65% of independent voters and only 56% of Democrats. “Democrats have simply not been given enough of a reason to come out and vote yet,” writes liberal blogger David Dayen. “The left is waiting for that long-promised ‘change’ they can believe in.”

Fund says that Harry Reid’s obsession with passing the bill may also hinge on re-election concerns. Trailing his most likely GOP opponent by 10 points, Reid may feel he’s a dead duck if his liberal base doesn’t turn out for him.

So the Senate death march continues. Many Democrats have grave misgivings about making the bill a top priority given the economy. But in the age of bloodthirsty partisan bloggers they dare not be fully candid. They can only hope their march doesn’t lead them right over the edge of a political cliff next November
