Meaning various “super delegates” had already confirmed for Hilary before the primary. Bit of a scam. Do the Republicans do the same? and how many have announced to date? This is how brokered conventions come into play, isn’t it?
However, out of 2,470 total delegates at the Republican National Convention in 2016, 437 are unpledged delegates, who play the same role as superdelegates. Of the 437, 168 are members of the Republican National Committee.
