Not sure what you personally consider to be a "viable candidate".
VIABLE
adjective
capable of working successfully; feasible.

He means it in the sense Biden may be mentally declining to the point he cannot do the job. I'm not completely sold on the cognitive decline issue but he does show signs of impairment.
I think it would be good if Kanye could give voters another option.
