Here is the NYTimes article:
Rivalry Remains Same, but Yanks Are Different from Friday, July 23, 2004:
"The pitching matchups in Boston are Jon Lieber (7-6) against Curt Schilling (12-4) tonight, Tanyon Sturtze (3-2) against Bronson Arroyo (3-7) tomorrow afternoon, and José Contreras (8-3) against Derek Lowe (8-9) on Sunday night, when the Democratic presidential candidate John Kerry, who sometimes wears a Red Sox cap on the campaign trail, will be on display for the New England vote."
I know. As soon as I heard that the media spun this as Kerry's surprise appearance, I hunted for and found the Times article to post, so that people would know it was a fraud. I even sent the link to Drudge with an explanation, to no avail.
