I agree that trying to diminish Clinton's victory, however small, is annoying, just as her constant attempts to diminish all of Obama's victories was, and is, annoying. I also question whether this is the final tally, since under Indiana's law those who cast provisional ballots have 10 days to get proper ID and have their votes count.
Obama made a point of congratulating Clinton on her IN win. Clinton made a habit throughout February of ignoring Obama's wins.
