I would say no to that. Neocons and RINOs are different. Possibly, Neocons are a subset of RINOs.
Neocons pretty much agree with each other. RINOs do not agree on everything. RINO pretty much means not sufficiently Conservative. There are a lot of areas that a RINO can be not Conservative. A RINO can be prolife, but in favor of amnesty for illegals. A RINO can be prochoice, but against amnestly for illegals. Those 2 RINOs might not agree on anything, but they’re both considered RINOs. Neocons agree with other neocons.
