absolute power corrupts absolutely.  (i.e. controlling every lever of power in government will give you the impression that you are utterly unbeatable and lead you to do things that you otherwise would not be so foolish to even contemplate, much less attempt to implement, like nominating a wholly-unqualified person to the highest court in the land)

it doesn't matter the political affiliation, although one hopes that certain political ideologies are less susceptible to the corrupting influencing of power, i honestly think that it ain't that way.

Even most of Reagan's policies were opposed by majorities in polling, so long as his identity was kept detached from them as I recall.

I'm hard pressed to think of anything they stand for that a majority would ever have supported--in the absence of Republican sponsored, Republican owned & Republican influenced national information infrastructure.

They create and distribute the common reality we experience, and their outright ownership or sponsorship gives them all the debate space that mass populations can access.

That gives them a certain edge in the P.R. game.
