Hillary appears to be terribly sick. There could be a possibility that she withdraws her candidature. I can't guess on what unpredictable Trump would do.
Another speculative probability is that since the presidential race gets short circuited, a public outcry may take place & Obama may take over & establish a Martial Law. That sounds legal...even if it's proven illegal...its legal!!! No peaceful transfer of power.....Lets hope, this speculation does not happen!!!
