Good question, Assuming the Dems win in November, I think some of the protocols need to be addressed.There seems to be a plan for if a president dies, if the VP dies (speaker takes over) not sure what happens after that. but little in the way of protocol for this situation, probably needs all 50 states to work out what should happen if a candidate can't carry on or steps down etc. So in future years any confusion or chaos can be avoided as much as possible, this would be in the interest of the USA and hte world too.
It usually takes something to happen before people think about what should happen in these situations.
