Your right about the rest but I was more talking about the Lindsay Grahams of the world . Rubio, Cruz and others who want a future have to be careful of how to time their support.
Neither Rubio nor Cruz ever said they wouldn't support Trump if he was the nominee, so I wouldn't count them as #NeverTrump. Like I said, there really aren't that many #NeverTrump Republicans who currently hold political office and are not already in the process of retiring. Most #NeverTrumpers are in the other categories I mentioned.
There are, however, many many current politicians attempting to hold some ridiculous middle ground, where they "support but don't endorse" the nominee, or something silly like that. It's silly, but I actually don't think those people who try to split the difference will pay any price for it beyond 2016, regardless of who wins the presidential election.
