Two Senators willing to filibuster plus the amount that backed out after yesterday's protests will make it very tough to get this bill to a vote.
This is absolutely not true. 41 votes are needed to prevent closure. According to Rep Lofgren the headcount for no votes on closure are down in the singe digits : http://www.reddit.com/r/SOPA/comments/onk34/urgent_message/
Once closure happens the bill heads into markup behind closed doors where the sausage making starts.
These bills are still very much on track. People need to be on the phones to their senators urging a no vote on closure so that the debate can happen in public with input from both sides.
That's not to say that the PIPA group will have 60 votes...just saying that Rand's attempt would've meant little before the PIPA coalition collapsed
