The Dream Act may not be dead. But it is most certainly on hold, and no one is sure for how long.
The U.S. Senate did not directly kill the bill. Rather, Senate Republicans filibustered the defense authorization bill. The reason was that the Dream Act, as well as the Don’t Ask Don’t Tell repeal, were amendments to the legislation. These two bits of conservative wolfbane were too much for Republicans to stomach. So they voted, en masse and without exception, to deny the bill’s passage.
