Let’s jump right in! Feedback? Drop me a line or just respond to this email.

This Week's Big Question
What does a wide playing field portend for the House midterms?
Democrats have slim chances to win a large number of Republican-held seats. Just look at the number of Likely or Lean Republican seats in my forecasts: According to my number-crunching, there are 95 Republican-held seats that are forecast to be won by less than 10 points by either party, but just 9 Democratic-held seats in the same category.
This wide, 100-seat playing field creates the chance that Democrats win a few fluke upsets in their path to a House majority. For fun, here are what some of those fluke wins would look like (PS: You can simulate your own wacky maps using my data which has been put to great use at
In this map, Democrats win Montana’s at-large district (they have a 31% chance today) Michigan’s 1st (a 17% chance) and 7th (25%), North Carolina’s 8th (21%), etc. The point being: all of these districts are projected to be Republican holds, but due to the nature of probability Democrats could easily win them.
Odds are that Democrats will win some unexpected seats. Keep in mind the this doesn’t guarantee a Democratic victory; they have just a 76% chance of doing so, per my forecast, and an 85% chance in the 538 model (which was tracking similarly unless the recent about of tsunami Dem wave fundraising reports). With 15 days left until the midterms, in which of these seats do you think the Democrats or Republicans will win unexpected victories?

A thread on @WholeFoods and elections: @Redistrict recently wrote that Dems will perform the best in areas that are geographically close to Whole Foods (WF). I decided to map/calculate the # of Whole Foods by congressional district to test his theory on WF and elections (1/9)

Opinion | How to Win Swing Voters (and How to Lose Them) - The New York Times
“This paper measures a “grandstanding score” for each statement that committee members make based on its intensity of opinion-giving and identifies which types of members of Congress and committees tend to use hearings to make their points. I argue that committee members grandstand in hearings to offset their limited legislative power. My findings suggest that such grandstanding behavior is more common among minority members under a unified government, and non-chair members of powerful committees, and in committees with jurisdiction over policies that the president wields primary power, such as foreign affairs and national security.”
