Are his knees buckling? That's the question some Democrats are asking tonight about President Obama in the health care fight.
Is the president deluded about bi-partisanship? Trapped into compromise on health care?
"A tightrope" is how a leading Democrat on Capitol Hill described the problem the president and his party face in this fight.
At a town hall today with Democratic activists, some worried he's too focused on winning over Republicans.
"My commitment to the American people is to get a good product which will include Republican ideas but...we're gonna get this done one way or another," he told the audience.
Still, left-leaning Democrats worry their leader's lost his nerve.
Obama appeared on Michael Smerconish's radio show, at midday.
"Joe" in Philadelphia called in to say "I, um, getting a little ticked off that it feels like the knees are buckling a little bit."
"Are your knees bucking? That's his question," asked Smerconish.
Obama responded "Well look my attitude has always been let's see if we can get this done with some consensus."
But opponents aren't dancing to that tune.
Key Republicans say the town halls turned them against the Obama plan.
"Its going to drive up the costs, its going to kick people out of the insurance they've got, and its going to cost too much," says Sen. Mike Enzi (R-Wyoming).
House Democrats plan a push without GOP help. Their problem is uniting Democrats.
The president's plan is not backed now by many conservatives in his own party.
