I wouldn't say ally. Let's just say deserving of honorable mention. NeverTrump does have a role to play in the mainstream media’s willful distortions of who Trump is.
In MHO NeverTrump is destructive within the political right. I have no respect for the more hard core among them and I pity the rest as being tragically mistaken.
A lot of NeverTrumpers are GOPe guys and therefore
not really on the "political right." A lot of them are just RINOs who fear that Trump will trigger the loss of their jobs or even subject them to investigation and prosecution.
I am a NeverTrumper for a completely different reason. In fact, most of the NeverTrumpers on TBR are probably in more-or-less the same category as mine. We have explained this over and over and over--to no avail, because Trump's supporters are not interested in any criticism of Trump; moreover, we have even cheered when Trump occasionally does the right thing--but this does not fit the Trump fanatics narrative to the effect that we just want him to fail.
In other words, we get falsely accused. (Heck, I want Trump to succeed. I just happen to think we nominated an unusually lousy Republican for POTUS. A lot of Trump's formerly ardent supporters are beginning to suggest
that.)
