Jon Lieber, Eurasia Group's head of research and managing director for the firm's coverage of United States political and policy developments, shares his perspective on US politics from Washington, DC.

This is what we're watching this week in US politics. It is, at long last, election week. The US has one of the longest most exhausting presidential election cycles in the world. That basically begins two years before general Election Day. And Tuesday of this week, it all comes to a conclusion. It's unlikely that we will know the results of the election on Tuesday night, although if Harris is significantly ahead in the early counting states, like North Carolina, that's going to be a strong signal that she's probably winning the overall electoral college. Seven key swing states to watch. Trump looks like he has the advantage in Arizona and Nevada. And the election, like it did in 2016, could potentially come down to the three so-called Rust Belt states of Pennsylvania, Wisconsin, and Michigan. On election night, Wisconsin and Michigan are likely to be known, but possibly not till late in the night. They were called for Biden late in the night on 2020.
