OK, I admit it, I got bored doing these. I started too early and the posts were too complicated. I'll be doing these less frequently until we get closer to the election. I've also switched to the 4-way RCP average including Johnson and Stein.
Here's the bottom line, the election has tightened up to be essentially a dead heat. Clinton is getting a slight bounce from her drubbing of Trump in the first debate but, at least so far, not a lot.
Polls Plus Model - Clinton - 60.1%, Trump - 39.9% - Trump +7.9
Polls Only Model - Clinton - 62.4%, Trump - 37.5% - Trump +6.6
Now-cast Model - Clinton - 70.0%, Trump - 30.0% - Trump +4.7
Real Clear Politics
Popular Vote - Clinton 43.9%, Trump 41.0%, Clinton +2.9 - Clinton +0.2
Electoral Vote - Clinton - 188, Trump - 165. Undecided - 185 - Clinton -41, Trump +31
Predict It Betting Odds
Clinton .68, Trump .32 - Clinton -.04, Trump - +.01
A couple of interesting observations. First, the betting odds haven't changed much and one has to wonder why. Second if the 4-way numbers are even close to accurate, whoever wins this election is going to be under 50% of the vote.
George W. Bush was under 50% at 47.87% in 2000. As a matter of fact Al Gore had more popular votes with 48.38%.
In 2004 George W. Bush got 50.7% of the vote. Barack Obama got 52.9% of the vote in 2008 and 51.1% in 2012.
The lowest popular vote percentages in the post-Roosevelt era are Richard Nixon in 1972 at 43.42% and Bill Clinton in 1992 at 43.01%. The "winner" of this election could come close to those numbers.
