Harry Reid is awfully confident the Senate immigration bill can clear the 60 vote threshold to defeat a potential filibuster, and I'm inclined to think he's correct:
“I talked about this to a number of my senators today, and what he wanted to say is they haven’t done a whip count on this yet,” Reid said. “I think we have 60 votes. Remember, we start out at 55 Democrats. I think the most I’ll lose is two or three. Let’s say I wind up with 52 Democrats. I only need eight Republicans, and I already have four, so that should be pretty easy.”
