Black GOP candidates a "novelty"?

In an attempt to illustrate the persistent American racial divide, Stuart Rothenberg, the author of this online article pulls the hackneyed stereotype off the shelf . . . "Legitimate Black Republican" is an oxymoron. Here's the main quote:

Strong black GOP candidates remain something of a novelty, and national Republican strategists are thrilled when they can find an appealing black to run for a high-profile office.

That assertion was only a paragraph after stating that nationally there were four Republicans (three of whom had the GOP nomination) vying for statewide office who happened to be black.

You know what is truly a novelty? A Democrat candidate for a statewide office; but I guess that didn't fit with the article's thesis.

Here's another post about a racism-mongering article.
