The Election Reduced to One Chart.

Today is Labor Day, the traditional beginning of the general election season. I have no changes to make to my previous forecast of Harris winning 292 Electoral Votes to 246 for Trump.   (This means Harris winning Michigan, Wisconsin, Pennsylvania, Nevada and Georgia while Trump wins Arizona and North Carolina.)

I. Polls, Betting Markets, Forecasts and Wishes.

Harris holds a modest lead in most national polls. Five Thirty Eight, the Economist and Nate Silver have up by about three and a half points. Real Clear Politics has her up just under two points. 

The Prediction Markets are very close. Predictit favors Harris slightly (54 cents to 49 cents) and Polymarket favors Trump slightly. (50% to 47%)

Most of the forecasts favor Harris by narrow margins. Five Thirty Eight has her winning 57 percent of the time. The Economist 52 percent of the time. Nate Silver has Trump winning something like 52 percent of the time but he has all but admitted that his model is suppressing Harris' vote too much because it's within two weeks of the DNC. (Put differently, she didn't get as large of a post-convention bounce than his model expected.)

So, you know.....close.

I for one am slightly more optimistic than these models. I think Harris has about a 65 percent chance of winning. I am of course biased in her favor. I want her to win. But the reasons for my optimism is that her personal approval ratings are about 10 points better than Trump's. That will make it difficult for him to change minds in his favor. 

Right now the median undecided voter is a normie who is sick of Trump's shtick. I believe they will be willing to turn things over to the next generation. Trump's job, as cynical as this sounds is, is to make that person afraid to turn things over to Kamala Harris. I think his attacks will get uglier over time but I don't think it will work on enough people for him to win.

He does not have the personal charisma, political skill, fund raising or even the personal energy to make that happen. He is old and declining. It shows more and more when he speaks and it is reflected in the less robust campaign schedule that he has been keeping compared to four and eight years ago. 

But campaigns are there to be won and stranger things have happened. A bit of bad news can always hurt the incumbent party and Harr is not yet running away with this thing. 

II. The Electoral Math.

We pretty much know what the result will be in 43 states and the District of Columbia. If we also assume that Harris will win Nebraska's 2nd congressional district and Trump will win Maine's 2nd congressional district, we can assume that the election starts with 226 electoral votes in the Democratic column and 219 in the Republican column.

That leaves seven swing states to decide the contest. There is an easy way to divide them-Northern and Southern. The three Northern swing states were all won by Biden last time and they generally poll to the left of the four Southern swing states.

If Harris wins all three Northern swing states, she will hit the magic number of 270 electoral votes. If she loses any of these states she will have to make up for it by winning a matching number of electoral votes in the southern part of the map.

Here's a way to think of it.  

1. Harris is expected to win 226 votes in reliably blue states.

2. She needs 44 more Electoral Votes to get to 270.

3. The quickest way to do that is to win the three Northern Swing States-Michigan (15), Wisconsin (10) and Pennsylvania (19). That puts her on exactly 270.

4. For every electoral vote she loses in the Northern Swing States, she must make up for them by winning that same number in a Southern Swing State: Georgia (16), North Carolina (16), Arizona (11) and Nevada (6).

Here a chart for what combinations of Southern Swing States would make up for losing one or more of the Northern Swing States.

That is the scorecard you need for election night. As the weeks progress, I'm sure I'll update my expectations. But the math on getting to 270 is pretty simple here. Harris needs to rebuild the Blue Wall of Wisconsin, Michigan and Pennsylvania or patch any cracks in it with an equal number of Electoral Votes from Georgia, North Carolina, Arizona and Nevada.

PS: I want to plug a new election forecaster for this cycle. He goes by Theo and I came across him on Twitter. (His Twitter handle is @ctolga_ )  

He has built a neat and visually appealing website for his forecast. His fore cast is considerably more optimistic than the older established forecasts. But I have a hunch that those forecasts are going to trend in his directions as the weeks go by.  Here is the link to his website:
