Just came across my twitter feed. No confirmation or reference link, but the tweeter is a news employee of NBC Washington - caveat emptor:
Ah, here we go:
A survey of South Carolina legislators shows there's enough support to remove the Confederate flag from Statehouse grounds if all supporters cast a vote.
The Post and Courier newspaper, the South Carolina Press Association and The Associated Press asked all lawmakers how they intend to vote. At least 33 senators and 83 House members say the flag should go.
That appears to meet the two-thirds majority needed from both chambers to move the battle flag. That rule is part of the 2000 compromise that took the flag off the Statehouse dome and put a square version beside a monument to Confederate soldiers.
According to the cited article, the 2/3rd majority requirement is 2/3rds of those voting, not 2/3rds of the full membership. Which would presumably make it easier.
I'm not finding the date the debate on the legislation is scheduled to begin yet.
