Bernie Sanders' campaign has requested a "recanvass" of voting in the Kentucky primary — not a "recount."
They are not the same.
What's the difference?
As NPR's Asma Khalid noted on air — a recanvass will "entail checking all of the voting machines and absentee ballots in all each of the state's counties to verify the accuracy of the vote totals."
In other words, individual ballots will not be checked. A recount would have re-checked how people voted on actual ballots.
