Just played through one as myself, set as a fairly inexperienced Republican from Vermont.
In the early campaign, Clinton was winning quite comfortably, only a handful of states were interested in voting for me - you know you're in trouble when you're losing Utah, SC, TN, KY and it's too close to call in OK.
After a tough fight, I managed to start level pegging with Clinton, and was neck-and-neck going into the final week. The states looked quite bizarre at that stage - I was ahead in California and behind in drawing even in much of the south and behind very strongly in South Carolina.
For the final week, I adopted Conor's Strategum of running ads in the final week (having saved my warchest in previous weeks). I ran three attack ads on Clinton's health care platform, while running a positive ad (ironically) on my integrity at the same time. The positive ad and one negative ad were run in all the states, and the other two negative ads were run in all states except for the ones I'd written off (Mass, Conn, Rhode Island, Maryland, Illinois, Arkansas, Colorado) and the states I was far enough ahead in (not many - Miss, Alabama, Texas, Nebraska, Kansas, Wyoming, Idaho).
The final poll, a couple of days before the election, looked like this (showing strong/lean/tossup) :
I spent the final couple of days in New York and Vermont and my VP in Florida and New York. The election night result ended up being:
Smid (R) 64,339,127 54.4% 455 EVsClinton (D) 51,285,665 43.4% 83 EVsBadnarik (L) 2,012,238 1.7% 0 EVs
Peroutka (C) 668,437 0.6% 0 EVs
My most pleasing result was Vermont, where I received 58.7% of the vote (whereas I expected to lose the state). My strongest result was Wyoming, where I received 81.8%. Also surprising was Rhode Island, which I'd written off as being out of reach.
The nation was remarkably unpolarised - most states I won were in the 52% - 55% range, with only a small handful in the 55% - 58% range. A fairly consistent result across the nation.
