"Election experts have identified Wisconsin, Michigan and Pennsylvania as states where "statistical anomalies" occurred, according to the Stein campaign."

I would let this play out before I decided that there is "simply no evidence" of wrong doing. It has been reported elsewhere that there is "credible evidence" of voting anomalies regarding the 2016 presidential election. I would think that voters on both sides would want true and accurate results, and if there really is in fact "credible evidence" that fraud may have occurred at any level during the election process then it should be addressed appropriately, whatever that involves. An investigation would put to rest any suspicions either way.
