Pretty funny that bookies think it's more likely that Kamala Harris wins the 2024 election than Joe Biden winning a second term. Just goes to show the kind of expectation people have for his term!

there's a long time until 2024, really hard to take any conclusion now.
I wouldn't rely that much on betting websites for that, gotta check how big is the sample (number of people giving their opinions)
I wouldn't trust that betting odds, that's not even available in bookies yet, so how can we verify that it's really what the bookies are thinking?
As long as people are satisfied with Biden's leadership, he will be the favorites in the betting, unless he will be like Trump.
