It feels like I've been doing this for years, but this is the next to last update. There will be a few more polls reported on Monday and then comes election day. The picture is getting very clear. Let's first look at the states in play
As before, the colors red and blue mean Republican and Democratic leaning respectively, purple means a flat footed tie under my system and the state with the gold background is the state both side need to win in the simplest path, which I call The Golden Spike.
As states are declared for one candidate or another on Election Night, the Golden Spike can move. I'll be live tweeting the updates under my Twitter name ConfidenceOfVic.

The numbers improved slightly for Romney and the median result is now 303 electoral votes for Obama and 235 for Romney. The median result is now the most likely result as well, which will happen if Romney wins all the states in which he is favored and the toss-up state Florida as well.
The numbers can't change all that much and that will very likely be the final answer I go with as my prediction when the last polls come in this Monday evening.
The Confidence of Victory number is now at 93.5% for an Obama win and 6.5% for a win for Romney. In comparison, Nate Silver has the number at 86% for Obama.
As someone who played a lot of backgammon back in the day, I know that 93.5% is not a lock. I played plenty of games where the final roll of a game came down to double sixes or double fives to win and the person who needed to get lucky did so. The favorite in that position had 94.4% Confidence of Victory.
One last electoral college update Monday night.
Stay tuned. Go out and vote if you haven't done so already.
This blog is still alive, just in semi-hibernation.
When I want to write something longer than a tweet about something other than math or sci-fi, here is where I'll write it.
