According to this AP report. Mike Ross (D-AR) has changed his mind and will opposed a government-run public option if it's in the final bill. He apparently listened to his constituents at recent town hall meetings.

Steny Hoyer, House Majority Leader, is also waffling on the public option.

UPDATE: The ADG has the report on Wednesday morning. The entire Arkansas congressional delegation is making noises against the public option but probably only because they no longer believe it can pass.
