It might be important I clarify that I'm not talking about the right, I'm talking about the far right (re-branded as the "alt-right"). This does not include most people who vote Republican or consider themselves traditional conservatives.

The traditional conservative movement is dying out. Quite literally, it has a demographic problem that it is not sure how to resolve. In it's place, you have the alt-right, which does tend to be more youthful, but which acts as an umbrella for a wide variety of extremist viewpoints, everything from extreme libertarianism to conspiracy theorists to white nationalism to single-issue anti-islamic advocates and a whole host of others. And within that milieu, a large proportion of people are not singularly committed to those hard-right ideologies as much as they define themselves solely in their rejection of liberalism, the left, or social justice. The result is a whole host of confusion. The alt-right is constantly infighting about cultural issues such as traditional masculinity or gay rights, to the difference between opposition to illegal immigration (a viewpoint which can claim to be more centrist) or opposing immigration altogether, including legal (which is held by the nationalist wing of the movement).

As the voting base disappears, these groups will have to figure out how to grow their movement, make political demands, maintain a presence without burning out, etc. Just like all movements do. But that's exactly where those intense internal divisions come in and wreak havoc.
