The Hill wonders if moving on to consider the DREAM Act in the Senate could open the door to a more wide-ranging debate on immigration:

If the supporters reach the 60 votes needed to proceed to the Dream Act, it could become a vehicle for other competing amendments and reignite debate on a comprehensive overhaul of immigration policies, which the Senate rejected by a 46-53 vote in June. A similar situation could occur with the so-called agriculture jobs measure.

This story says, though, that sections of the Democratic leadership (Durbin) say they want to keep debate on this bill "focused"--will other members of the Senate oblige them?
