Excuse me for asking but what the **** does Dubya mean when he talks about "Democracy", "Democratic freedoms?" and "The Forces of Democracy" Seems not what I thought he meant.

Bush is confusing "democracy" with "capitalism". He's not making the world safe for "democracy" or spreading "democracy". He's using "democracy" as a code word for "cronyistic capitalism". And it's cronyistic capitalism that he is really promoting around the world.

So "One Man (or Woman) One vote" is not a cornerstone of a Constitutional Republic? I take it then that Proportional Representation is definitely out of the question?

No, "one person, one vote" is not a cornerstone of this constitutional republic, although there are many people in the US who don't understand that fact. We most certainly do not have proportional representation.
