the question voters aught to be asking of their 2 respective parties is how do we keep a straight face and believe that 2 70 year old men are capable of performing the hardest, most stressful, most important job in the world.
These are the probable candidates, selected by the system we have, which has worked pretty well for more than two centuries. The question you seem to be asking is whether the established, legal, accepted way of choosing candidates should be abruptly abandoned if we don't like the result. That is what makes it hard for me to keep a straight face.
