There are changes that must be made to the laws regarding who can be the US President & even be qualified to run for the office. But they may never get done due to politics, and mainly because it would require a constitutional amendment passed by 75% of states, which would affect mostly the red states.

People with felony convictions should not be allowed to be President or even run for the office. Felons aren’t even allowed to vote in all but 2 states. The age of candidates should also be raised to a minimum of 50 years old on the date of the election to get a more mature person. The laws preventing those who engage in insurrection should be clarified to say that those who are convicted of insurrection & sedition are barred from running or being President.
