BTW...any person who gives a speech, especially if it's prepared by a "speechwriter", should review the speech before it is delivered. If they note an error they should call attention to it and have the speech amended. Off the cuff speeches are a reflection of the inner workings of their own minds and give a more definitive view of their thought process.
There should be no "mistake" in speaking the word democracy. Politicians are supposed to know the difference, and they either don't know and shouldn't be in office, or they know and it is intentional.
If nothing else they could even ad lib in the word Republic, but they don't, and that is the most telling thing of all!
The speech is not a mistake at that point, it is given with intent.
I'm just not buying it broomhilda.
