Will centrists sit out the 2018 general elections?

[P. Clodius Pulcher did nothing wrong]

At this point, true centrists should be firmly in the democratic camp. Centrism is more or less dead in the GOP currently, with a select few exceptions in the senate. With a few exceptions I would argue that self-identified centrists voting for the GOP are actually republicans and not centrists.

I shouldn't have to explain that you can be both on a political forum like this, but whatever.

If you read the very lines you quoted you would see that I write that "centrism is more or less dead in the GOP". Indeed, if you are a "centrist republican", you should feel very alone these days. Unfortunately. I wish it was different. I wish america had two respectable parties. That is not the case right now.

You said "actually Republicans and NOT centrists," implying they can't coexist, though. 

I think they mean that the generalized Republican leadership/elected officials are not centrists, and that therefore "Republican centrist" voters (as opposed to their representatives) no longer have a home in the party, and should be voting Democrat if they're actual "centrists"
