I like the idea, in theory, of Laura as the mayor. She gets to mix it up with different characters, and I'd get a kick out of Luke and Laura both being mayor of Port Charles.
However, except for Luke's brief stint, when have Port Charles Mayors ever been front burner? I mean the Mayor story was the bone they threw Felicia a couple years ago, and it didn't give her much.
I really, really have my doubts that even if Laura became mayor it would've lead to her being front and center.
