In the Fargo episode The Gift of the Magi Ronald Reagan (portrayed by Bruce Campbell) is campaigning for presidency and Lou works as his security detail. They have a conversation in the toilet where Reagan compares (rather inappropriately) Lou's service in Vietnam to his own role in a WW2 movie. Later when Lou asks:
Governor, I don't mean to, uh What we did over there, the war? Um and now? My wife's got lymphoma. Uh, Stage III. And, uh, lately, the state of things, uh Well, sometimes, I late at night I wonder if maybe the sickness of this world, if it isn't inside my wife somehow. The-- the cancer. I don't-- I don't know what I'm saying, except Do you really think we'll get out of this mess we're in?
Reagan is unable to give any answer, apart from some standard political nonsense and patting Lou's back. The (almost) whole scene can be seen here.
This depiction of Reagan makes him look like an unpleasant, not very social or wise person.
This seems to be in contrast with what can be read on Wikipedia:
Reagan's ability to connect with Americans earned him the laudatory moniker "The Great Communicator." (...) Reagan was known to joke frequently during his lifetime, displayed humor throughout his presidency, and was famous for his storytelling.
Moreover, in this article the showrunner Noah Hawley says that Reagan has a key role in the show, but as an indicator of changes. He clearly states that presenting his views on Reagan was not his intention:
I don't have a moral opinion on Reagan; that's not part of the show.
Taking above facts into consideration why the showrunners showed Ronald Reagan in a negative light?
