Answer:
i am not sure because i wasnt into politics in 2016, system was either rigged or people praised trump more because he was a good guy when he wasnt.
Step-by-step explanation:
in 2020's election trump didnt win because he wasnt getting enough votes in each state to win. in the live stream (the first debate), trump kept interupting biden, trump faked having corona as an excuse to not debate for the 2nd attempt.
The votes took very long to get processed and trump kept saying the election was rigged so he could become president. Biden was officially the president on january 20th, 2021 because more people voted for biden after the election too. Since he ran to be president the 2nd time in 2020 of november, that was his second time so he cant become president again cause he ran 2 times.
