Christie's Town Hall: A Challenge to Stop Trump

Maggie Haberman said that it was difficult to find actual Republican voters at Christie's town hall and that apparently almost every single voter that they talked to was a registered independent. Do you think that part of a strategy for Christie could be getting Democrats and independents to vote for him in the primary just as a way to stop Trump? Is that like a realistic possibility? I don't think that's a real strategy, but because independents can vote in either primary just by showing up on that day or non-MPa affiliated so there was non party affiliated MPa voters.
