(Ladies PLEASE: this is a discussion of word usage, this is NOT going to be a discussion regarding the merits of Fred Thompson or any other presidential candidate of either party, or any other candidate for any other office, I'm just using Thompson as an example because he's the most recent person relating to my question)
So the headline is "Fred Thompson to announce his presidential candidacy on September 6": erm, if he's saying that he's going to announce it then, isn't he in effect already making the announcement ? The announcement of whether or not it's going to happen should come more or less out of the blue?
