Well, okay, but my request was not so much for evidence of voter suppression but evidence that "voter suppression played a part in Clinton losing states that she otherwise would have won".
I think that the article does suggest at least Wisconsin could fall under that category. However, with the state only won by 30,000 votes, would that number have voted for Sanders making the voter suppression irrelevant?
If, for example, Sanders had won Wisconsin, Michigan and Pennsylvania that would have been 46 electoral college votes.
Trump's final total of 304 - 46 = 258
Clinton's final total 227 + Sanders's extra 46 votes = Victory.
The question here is who in those states thought that voting Clinton would be a good thing but that they couldn't vote for Sanders?
And if Sanders was running, who among those who voted for Trump may have voted for Sanders?
I don't know the answer but anecdotal evidence tells me that at least 2(!) people who I know from Michigan would have voted for Sanders, one of whom voted for Trump and the other decided not to vote at all because he thought a choice between Trump and Clinton was no choice at all.
