With much of the alt-right freaking out over the Syria strikes, I wonder if we're going to see an evolution of the Trump movement into a state where they become the new McCains, so to speak -- not on policies, obviously, but on the jumping off the bandwagon and broadcasting their displeasure to an audience made up of the other side, every time their side does something they don't like.
The other side being the Sanders supporters, in this new alignment of parties.
Strangely, the alt-right will be seen as the "moderate" or "sensible" Trump supporters, who do not fall in lockstep with their movement on every issue, who are eager to "reach across the aisle" -- to the Bernie people.
True, on ideology they are more extreme than the unshakable Trump supporters, just like McCain is way more out-there on ideology than McConnell or Ryan.
But in terms of emphatically and dramatically showing their non-partisanship, the analogy looks fitting.
Also, the "sensible" Republicans of the past cycle were more concerned about finding a mate from the other side, rather than someone from their own party and social-cultural background.
Likewise we see the alt-right pining after secular / leftist exotics, rather than an American girl whose uncle wears a camo Trump hat out in public.
I attribute this greater desire to please the other side to a greater rootlessness. If you're a nomad, there is no "your people," and you have to rely on connections with unfamiliar groups. If you're deeply rooted, you've got that social-emotional sustenance already, and what the out-group members think of you is irrelevant.
