On Thursday, Rockefeller admitted he expects little bipartisan support.
"There is a very small chance any Republicans will vote for this health-care plan. They were against Medicare and Medicaid [created in the 1960s]. They voted against children's health insurance.
"We have a moral choice. This is a classic case of the good guys versus the bad guys. I know it is not political for me to say that," Rockefeller added.
"But do you want to be non-partisan and get nothing? Or do you want to be partisan and end up with a good health- care plan? That is the choice."
