Was the election stolen?

At the risk of sounding like Loftus, Let's look at this from the point of view of an outsider. Suppose I come here from a foreign country. I am not a Republican or a Democrat. There are all the sources of information out there. I am trying to figure out whether the election was stolen. How would I assess the evidence on this matter? By what neutral criteria should I take, say Sean Hannity seriously and Rachel Maddow not seriously? Both, no doubt, have an axe to grind. But you can grind your axe with facts, or with "alternative facts." Or are we stuck with the Nietzschean conclusion there are no facts, only interpretations of facts. (Is that a fact?)
