Similar statements were also issued from four other senators: Patty Murray (D-WA), Ben Cardin (D-MD), Jeff Bingaman (D-NM), and Amy Klobuchar (D-MN).
To be clear, these are not signatories to a letter--circulated by the three groups--advocating the public-option-through-reconciliation strategy. PCCC co-founder Adam Green put it this way: "We're accepting clear statements that if the public option comes up for a vote, they would vote yes. We're debunking what [White House Press Secretary Robert] Gibbs said last week, that the votes don't exist -- they do...we'll prove it."
So far, 24 members have signed the letter, and five have issued statements indicating their support for passing a public option through reconciliation. Senate Majority Leader Harry Reid also stands behind the idea in principle. That means Green et al. have 20 members to go.
