Oh, hell!
I thought it was perfectly acceptable to use the correct spelling of a person’s name when referring to them.I too use “Obama” at times, as I used “Bush”; “the President” at other times (for either of them) ; or “President Obama” at still other times (just as I used President Bush”).
One of those forms is incorrect?
Only when it is partisan bitching. And how many times have we heard “Mr. Bush” or “Mr. Obama”? Both are incorrect.
