I don't know of any RINOs in Congress. Locally the story might be different, but even so I stand by my assertion that Republicans are far more unified than the Democrats (as the Democrats are split federally as well as locally).

Romney, Collins, and Murkowski are RINOs. Previously, McCain and Flake were.

Republicans are split: libertarian, nationalist, religious

> What about the Trump faction vs. the RINO's.

There are factions in the Republican Party, but for various reasons they are much more prone to have the non-dominant faction submit meekly to the dominant faction in terms of most actions in government, and even most public statements outside of contested primary campaigns. And even there the actual policy disputes are often not front and center.
