50/50 at best. As mentioned previously, I'm referencing the betting odds. So even if you ignore poll bias or bias interpreting the results of polls for the news, betting shops and financial markets (also betting on Trump) don't want to throw away money.
My point is that even if Harris wins it should not be anywhere near this close, Trump shouldn't have a snowballs chance in hell of even getting 10%, but here we are. Roughly 50% of voting Americans are willing choose him over Harris. That's insane.
