Congress has been trying to come up with a FISA bill that will be free of some of the short-comings of its predecessor legislation. The House has now overwhelmingly passed a bill that includes retroactive immunity to telecom companies that may otherwise be liable to lawsuits for helping the government eavesdrop on suspected terrorists.
The left is upset that the immunity provision was included. This puts Senator Obama in a sticky wicket since he supported the bill when it was in the House, but now that his base is aroused and angry he has reversed course and promises now to filibuster the bill that he previously supported.
In other words, as with public financing of his campaign, Obama was in favor of it before he was against it. The senator is sounding like a clone of John Kerry.
