Who will win the presidency?

Want to know what people think will happen? I feel like a lot of games are being played currently to get the advantage. With Trump being shot at, it rose his stock with his party, and maybe won some people over with how atrocious the attack was. On the other hand, I feel Biden stepping down is also a political power play and an answer to Trump being shot to sway momentum. I don't understand though how Kamala Harris is the nomination even though she was never nominated for the position. It's not like she is taking over right now. Thoughts?
Donald Trump
Kamala Harris
