The comparison is completely faulty; in 1968, the primaries didn’t START in December or January, but much, much later. So It wasn’t unusual for big states to be decided later than now.

Is she breaking any election rules set by law or Party by staying in the race? If not then people should just back off and let the system work according to the rules rather than according to who can best pressure their opponent out of the race. She represents her supporters. They have a right to see her do all that she can do to win.
