Did she campaign in Wisconsin after the Democratic primary? Did she campaign in Michigan outside Detroit, Lansing and Ann Arbor? Did she campaign in Pennsylvania outside Philadelphia, Pittsburgh and Harrisburg?

Same argument, every time. You know why she didn't campaign there? Because Democrats won those cities so many times prior it would have been stupid to assume she would lose. Every political statistician in the world would have recommended she made the exact same moves.

but somehow Obama was able to win in 2012 with those same districts.

You're right! He did, despite not campaigning there.

Let me ask you this. Do you deny that Russian propaganda, gerrymandering and voting booth tampering played a role in the election? I'm just trying to get a baseline understanding of how much or little you think these things played a role.
