Clinton Wins PA: By rounding off, an illusion of a ten-point win is created, but the real margin is 9.32%(54.66%-45.34%). The difference right now between a "double-digit", decisive victory for Clinton and a mere single-digit, superficially close moral victory for Obama (after rounding down) is less than 3,800 votes, out of more than 2.3 million votes cast.

UPDATE [4/24/]: With all the votes counted, the actual margin of victory ended up being 9.1%. Had a mere 1,200 votes switched, her margin would have sank below 9%, and after rounding down, the headlines would have been that she won by "8%."
