No, it isn't. Do you even know the definition of sedition, or of treason? How about looking them up?
Because having a "shadow" Administration that just speaks up on issues doesn't qualify as either. It's the same as we have with the party out of power criticizing the one in power, except with completely informal titles attached. It's pure free political speech/free assembly. And as I said, the Dems won't be able to pull it off because they don't have a strong enough party hierarchy.
Were you so eager to shut down lawful dissent during the Biden Administration? Because if you try to do it now, it will happen to us next time. Although as I said, the Marines aren't going to help you out on this one.
I do know what it is and come from a USMC family and am close personal friends with G7 level command.There is a such a thing as Constitutional opposition which in a sense a “shadow” which provides legal oversight. Then there is the illegal kind like what Obama has done and still continues to do which is treasonous and subversive. This is nothing but semantics here.
