Who could vote if Michigan re-does primary?

I voted for Romney. He's gone. Now I want to vote again!
Heh....

Will GOPer voters be the difference in the Michigan primary?
"Obviously they would have to make those decisions how they're going to run this, how they're going to pay for it in the next two weeks. The legislature is only in for the next two weeks, and then they go on break, and then it's too late. So, really, within the next two weeks they have to make a decision on this.'"
