What are you wishing for Lauren Martinchek? Having an exclusive club that then tells the majority of the population what to do? I don't know what kind of democracy you are indulging in. John Kasich, regardless of whether you agree with him on every issue, is a sound voice to be heard and absolutely at a Democratic Convention. We also can think straighter ourselves when genuinely listening to voices from a different view points.
During the course of this election, Kasich has been helpful to Democrats on a number of issues if only they were listening.
