It is not what is "conceivable" but what is constitutional, conservative, prudent, likely. These people want and intend to wield power over us. We have a Constitution to protect us against exactly that, a federal government exercising powers beyond its mandate. We have history to tell us about entrenched bureaucracies. We have history to tell us about unaccountable arms of government.
We have a recent campaign in which everyone who was not Trump-correct was labeled a globalist and a slave of Goldman Sachs.
That was then, this is now.
There's no reason that whatever President Trump does couldn't be "constitutional, conservative, prudent", etc...
