Inaugural speech inevitable quibble with accuracy

I imagine somebody caught this in pre-speech vetting, but decided it would be too confusing to use the correct number:

Forty-four Americans have now taken the presidential oath. The words have been spoken during rising tides of prosperity and the still waters of peace. Yet, every so often the oath is taken amidst gathering clouds and raging storms.

For the record, it's only 43- Grover Cleveland was sworn in twice, non-sequentially. Despite being nicknamed "Uncle Jumbo," Cleveland only counts as one American.
