Kamala Harris’s odds of winning rose from 50% to 56% in the final update of the Economist’s statistical forecast, noting, however, that this is a small lead, which could be overturned.

In particular, as the Economist notes, Kamala Harris strengthened her image at the end, a fact that was also demonstrated by the latest polls on which the medium’s prediction estimate was based.

The Economist emphasizes, however, that a Trump victory is not excluded.

Of the 67 surveys released on Monday, 44 gave Kamala Harris better ratings, the publication said, which appeared to boost her ratings especially in the Rust Belt (a region of the Northeast United States, the Midwest United States, and much of northern parts of the Southern United States). He led by an average of one percentage point in six polls in Pennsylvania, the most critical of the swing states, and by the same percentage in five polls in Wisconsin. In Michigan, another ambivalent state, five polls have it up by an average of two points.

But polls in the Sun Belt, a region of the United States generally considered to stretch in the southeast and southwest, were less impressive for the vice president, showing her trailing by an average of one to two points in Arizona, Georgia, Nevada and North Carolina.

But the results were better for Harris than those of previous polls in those states by the same companies.
