One of the Senate's most liberal members seemed open to passing a scaled back healthcare bill on Wednesday, shrugging off many liberals' concerns.

Sen. Bernie Sanders (I-Vt.) signaled that a less comprehensive bill might be worth passing if it's the only option for passing health reform.

"I think that if what we end up passing may not be as comprehensive as some would like, so what?" Sanders said during an appearance on MSNBC.

"We all know about Massachusetts," Sanders said, in reference to the GOP's special election victory in the traditionally Democratic state last week, which gave Republicans enough votes to sustain a filibuster in the Senate.

That victory forced Democrats to scramble to evaluate their options. Some have advocated a so-called "sidecar" approach that would see the House pass the Senate bill, and then craft a separate bill with fixes, which would pass through reconciliation in the Senate.

That strategy was put in doubt, though, when a flurry of centrist Democratic senators rejected using the budget reconciliation process, which bypasses the 60-vote filibuster rule.
