"Although we strongly support the important reforms made by the Senate-passed health reform package, including a strong public option would improve both its substance and the public’s perception of it," Bennet wrote to Reid in a letter cosigned by Sens.

"The Senate has an obligation to reform our unworkable health insurance market -- both to reduce costs and to give consumers more choices," the senators added. "A strong public option is the best way to deliver on both of these goals, and we urge its consideration under reconciliation rules."

Reid had opted to exclude the controversial public insurance option from the Senate's bill after it became clear that he wouldn't be able to muster the necessary 60 votes to pass a bill including the measure.

Since the Senate passed its bill in December, Democrats have lost their 60-vote majority and have been examining options to finish the legislation.

One option under consideration would be for the House to pass a series of fixes to the Senate's bill in order for the whole package to pass muster with House Democrats. That bill -- a so-called "sidecar" bill -- would then pass through the Senate using reconciliation.

Over 100 House Democrats have signed onto a drive similar to Bennet's, calling for that sidecar bill to include provisions reestablishing the public option.
