If Romney wins virtually no states for the rest of the primary season there's no way he will be nominated at the convention.
Except that that's not going to happen. NY, UT, and CT should be in the bag for him. He has to be favored in IL as well. I'm not sure about NJ but I see that probably going his way, same with MD. IN, WI, and OR are probably where you're going to see whether we get a brokered convention or an outright Romney victory. In this situation it's nearly impossible for Santorum to win in delegates and very hard to see him pull ahead, even with PA and TX.
This is of course assuming Gingrich stays in, which seems to be the case. If he gets out then all bets are off, because suddenly states like MD and IL are competitive, and those three I mentioned above (IN, WI, and OR) look very good for Santorum.
