Keeping the "suck" in "successful"

I’ve heard accessories called “assessories,” and succinct pronounced “sussinct” (not so often, but then it’s not so common a word), and flaccid started down the road to flassidity so long ago that the wrong pronunciation is now right. (That is, all our dictionaries list it, some as the majority usage.) Still, most English words with this Latin-derived double-c -- originally pronounced kk, as John Wells explains at his phonetics blog – continue to sound the cc as ks: accident, success, vaccinate.

But just as there’s no apparent reason for succinct to change its sound, there’s no way to know when another new pronunciation may appear. A couple of weeks ago, I had my first encounter with the nouveau successful, pronounced “sussessful.” The speaker was a caller to “On Point,” WBUR-FM’s talk show, who hailed from White House, Tenn., and who predicted an electoral victory for Mitt Romney. Why? “He’s a sussessful governor and a sussessful businessman as well.”

Yes, he had a Southern accent, but my Southern-speaking friend doesn’t recognize this as a regional thing, and of course it could be idiosyncratic. Anyone else out there hearing – or saying – “sussessful”?
