Senate Democrats had hoped the chances for a health care reform bill would get a boost when Sen. Olympia Snowe, R-Maine, supported it.
However, moderate Democrats are still not eager to get on board, Politico reports. They are worried about voter reaction to government control and cost issues.
They're also waiting to see if the White House and liberal senators will try to push for a public option that would allow the government to sell health insurance.
Democratic leaders are trying to get 60 votes to shut off debate and pass the legislation.
Still, one thing both sides agree on is that the process is exhausting.
"We just finished the first quarter. There are three quarters to play," said Sen. Ben Nelson, D-Neb.
"The bench is worn out. The quarterback keeps getting sacked. And the crowd has about had it too," he said.
