“If top medical experts decide it’s likely Clinton will suffer another fainting spell, regardless of the treatment she is given, the mood among New York Democrats is that now is the time to find a replacement.”
Hmm...
The time to identify a replacement for Hillary Clinton is long since passed. That window closed when the Democratic Presidential Debate Cycle ended.
Massive snowballs (all 50 of them) have already started rolling downhill as ballots are printed, early voting begun, and absentee ballots mailed out to voters. Those are three major issues that would have to be solved with less than 60 days left before the Presidential elections.
The real fun will come when legal challenges are added to that mix. And add to that the Constitutional issue - there is no provision to delay the nation-wide Presidential vote.
Things are shaping up rather quickly to make the post 2000 Presidential election look like a very minor issue.
