Re:

"Obama boasts of spending a billion dollars on his re-election campaign."

Got a source for that?

Do you see my name as the author of that article?

His web site is at the end of the article. Contact him and ask.

I will say that I have read that Obama's goal is to raise a billion dollars for his re-election.

You could enter the key words, [Obama - billion dollars - re-election] in a search engine.
