His mind has been warped by decades in politics. He was raised just like many other young boys. During his teen years, he dreamed of owning a car, his own house, and thought he may some day have his own family, although that last thought seemed so far away. Sometimes we see glimpses of the young Biden when the demented synapses of his mind line up in just the right way that he gains access to those memories during press briefings and campaign speeches. 

Biden's youth was cut short when he successfully became Delaware's youngest senator at just 30 years old. Perhaps he avoided it at first, but the new ethics of DC politics began to shape Biden's character. Gradually, the catholic virtues of his youth were replaced with the new virtues that would help him succeed as a politician. Prudence was replaced with cunning, justice with deceit, and charity with pandering. Above all else, Biden learned that he must do whatever it took to gain more sweet campaign contributions to be reelected. 

As the decades rolled by, these new virtues began more and more to define who Biden was. By the time he became president, he was far past the point of recalling who he might have been as a child. The world of politics had etched itself into his soul, and he was more politician than he was a man from Pennsylvania. And so when this election cycle rolled around, Biden was not capable of doing anything more or less than getting those sweet campaign contributions again and running for reelection.

to be fair being 30 in the 1970s is like being 50 today

also biden was always a corrupt, sadistic, racist shitstain. he did literally enter politics to fight integration lol. he did not have some set of staunch principles that were eroded by washington. he immediately became known for being a greasy creep that was for sale to the credit industry.

if anything this slurring, demented zombie is a major improvement over young biden, the glib white supremacist and puppet for the worst lobbies in the country.

That's true, but it was taking too long to write and I didn't know how to incorporate that. If the question is about why Biden is trying to run again, then the response needed to be about what's compelling him to do it. You have my permission to alter the story to be truer to Biden's real character.
