From HuffPo:

The Senate Finance Committee narrowly passed an amendment Thursday from Sen. Maria Cantwell (D-Wash.) that moves the conservative panel as close as it will likely get to a public health insurance option.

The amendment creates a "federally funded, non-Medicaid, state plan which combines the innovation and quality of private sector competition with the purchasing power of the states,"

Baucus and Conrad voted for it; Lincoln and Snowe against it.
