Senate polls in individual states have moved around…but the Meta-Margin and the average seat count have stayed stable. Nonetheless, the crystal ball is cloudy. Why is that? The midterm polling curse.
As I wrote last week, everyone’s calculations are, to an extent, built on sand. Historically, in any given year midterm polls have been off in the same direction by a median of 2 or 3 percentage points. Depending on the year, either Democrats or Republicans end up outperforming polls. In current poll medians, six races are within less than 2 percentage points: Alaska, Colorado, Georgia, Iowa, Kansas, and North Carolina. Therefore all six of these races could be won by Republicans…or all six could be won by Democrats.
The other races total 48 Republicans and 46 Democrats/Independents. Republicans are slightly favored to take control, since an even split of the six close races would give them the 51 seats they need*. However, the likely possibilities range anywhere from a Republican majority of 54-46 to a Democratic majority of 52-48. As of today, cranking through the math and the uncertainties gives a probability of 55% for a Republican takeover.
I am thinking about how to guess on Election Night where in this range the race will land. Here are my current thoughts. After feedback, I may turn them into a printable scorecard. [Read more →]
