In fact the deep state isn't widely being used on the right to explain the incompetent GOP. The deep state was being accused of trying to sabotage Trump in general, not the GOP in general (was, because most of that early hysteria has died down). The premise was that the deep state disliked the political idea of Trump ushering in greater isolationism, involving pulling back from policing the world and the military industrial complex with its perpetual war machine.
The modern deep state concept has been widely discussed on both sides of the aisle and has been credible for decades, going back to shortly after the founding of some of the very large and powerful US Government institutions, such as the CIA, FBI and NSA among others - all of which have their own gravity in the politics of the US. It's not a conspiracy, it's the inherent nature of government, politics and power. Nearly every government on the planet will have its own active version of the US deep state, only varying in the specifics and size not the concept.
There's absolutely nothing right-wing about it, either in believing it exists (there's nothing to debate there), or being concerned about it (the left and right were both extremely concerned about its use and power during the Nixon era for example).
