Mrs. Fiorina, Mr. Kasich, and Mr. Bush.
Mr. Rubio has been lurking in the periphery of the 'still not ruled out' field. I don't recall why I would have eliminated him, but something in the back of my mind keeps telling me that I have. So I guess he's not really ruled out yet, at least not until I remember why I would have or he gives me other reasons to.
And, as a personality, I like him more than most of the rest.
To be clear, none of those represent check marks yet. They just don't represent Xs yet. The order in which candidates get Xs is likely happenstance to some degree, it doesn't speak to some sort of ranking. It's when I hear enough things from them to add up to a - no, I don't think I can vote for them. Those things often have to do with pandering to ignorance or nonsense, telling people what they want to hear rather than what they need to hear.
