I apologize if this is in the wrong forum, but since it has to do with trends, I thought it belonged here.
So I did the math and found out how Democratic/Republican each state was compared to the nation as a whole in 2012 by subtracting 3.86% from the Democratic margin, because Obama won nationwide by 3.86%. That is what I call the 2012 "basemap".
I would've done this myself, but fortunately Dave saved me the trouble by including a "trend" map in the presidential elections, which shows how much more Democratic/Republican each state became since the "basemap" of the last election, or in this case, from 2008 to 2012. I added each state's trend to its 2012 margins, and created what I expect the 2016 "basemap" to look something like.

Of course, this is assuming that the trends remain the same from 2012-2016 as they were from 2008-2012, which is extremely unlikely. Still, I find it interesting how, from the 2012 basemap, Michigan and New Mexico go from being Democratic-leaning states to swing states, and North Carolina goes from being a Republican-leaning state to a swing state.
