Understanding the Methodology Behind the Polling Data: A Detailed Explanation

The latest polling data from The Telegraph’s national voting intention tracker shows a tight race between Kamala Harris and Donald Trump in a potential head-to-head matchup for the 2024 presidential election. The methodology used by The Telegraph relies on a variety of US polls aggregated by FiveThirtyEight, with only polls of registered voters considered.

The polls are weighted based on the grade assigned to the pollster by FiveThirtyEight, taking into account past empirical accuracy and methodological transparency. Low-rated pollsters are ignored in the analysis. The data is updated hourly, and a locally estimated scatterplot smoothing (LOESS) model is used to fit multiple regressions over subsets of the data.

In terms of electoral college votes, an average of the last five polls from each state is taken into consideration. States where either candidate is polling five or more points ahead are considered “solidly” in their favor, while states with a lead between 0.5 and five points are deemed to be “leaning” towards that candidate. States with tighter margins are labeled as “tossups.”

The swing state tracker charts the latest five individual polls in each 2024 battleground, providing a snapshot of the current state of play in key states. Approval ratings for Joe Biden and Kamala Harris are compared to those of Donald Trump at the same point in his term, giving insight into the public’s perception of the current administration.

Overall, the data paints a picture of a closely contested race between Kamala Harris and Donald Trump, with both candidates vying for the support of the American electorate as the 2024 election approaches. Stay tuned for more updates as the campaign unfolds.
