Personally I doubt Clinton would ever give up the nomination voluntarily, but it's another twist in American politics. Personally I think it would be the best result for everybody!
http://www.telegraph.co.uk/news/2016/09 ... ection-ra/David Shuster, a top US journalist, says that the election has entered “unchartered political territory” after Mrs Clinton’s diagnosis.
He quoted a Democratic party operative as saying: “Expect an emergency Democratic National Convention (DNC) meeting to consider a replacement.”
The source confirmed to Mr Shuster that Mrs Clinton would have to voluntarily give up the party nomination, saying: “We can make contingencies, argue, plead with her, but DNC bylaws are clear her nominee status is now totally up to her.”
Should Mrs Clinton drop out of the race, the DNC would hold a special meeting to vote for a successor. Party rules indicate that a new nominee would be elected by a simple majority vote.
No special consideration would be given to Tim Kaine, the current vice-presidential candidate, or Bernie Sanders, Mrs Clinton's closest rival in the race to secure the Democratic nomination. And if someone other than Mr Kaine were selected, he would remain the vice-presidential candidate.
When the unlikely possibility of Mrs Clinton dropping out was raised months ago amid the furore surrounding her emails and whether she would be indicted, Mr Biden was widely considered the likely replacement at the time.
