Least divisive of the last 5 Presidential elections?

[twenty42]

I remember 2012 being a much less emotionally charged election season than 2004, 2008, or 2016. 2004 had the wars going on and the Bush hate from the left, 2008 was a big deal because of Obama (and Palin, to a lesser extent), and 2016 goes without saying.

I also remember the 2012 election season itself being unusually quiet compared to the other three. Election fervor began to sweep the nation by 2007 and 2015, but media coverage in 2012 didn't really heat up until the conventions. I guess there wasn't much to talk about, with an incumbent president running and a pretty uneventful primary from the Republicans.
