Polling aggregator FiveThirtyEight has named Vice President Kamala Harris as the narrow favorite to win the presidential race on Election Day, shifting from former President Donald Trump for the first time since October 17.
Harris's lead is razor-thin, with FiveThirtyEight’s model showing her winning 50 out of 100 simulations compared to Trump’s 49. Similarly, Nate Silver’s model in The Silver Bulletin also slightly favors Harris, giving her a win in 50.015% of cases.
Both forecasts emphasize the unprecedented closeness of this race, with Pennsylvania as a key battleground.
50.015% literally means that neither candidate is favored to win. Take out a coin, assign Harris as heads and trump as tails, now flip the coin a bunch of times - and that's exactly how often Harris or trump is likely to win the election
EDIT
Nate Silver just posted his final pre-election blog post and he explains very clearly that this is a dead even race. Either candidate is just as likely to win as the other candidate.
