I'm Canadian and cannot vote in the US election, even though it'll affect us a lot (when a sleeping elephant rolls over...)
However, it drives me nuts looking at US polls. Harris is ahead by 2.4 points on average, which translates to something like 5-6 million in popular vote. But due to the electoral college system, it's still a tossup! 538 is running monte carlo simulations based on state-specific polling and margins of error, and Harris is only winning ~54% of the time. https://projects.fivethirtyeight.com/2024-election-forecast/
So I say this kindly, as your northern neighbour, please please go vote :D
We will likely have our own election in 2025 complete with buffoonery.
