If ever some non-tabloid sources chime in with this, I'll start taking it seriously. But for now, I'm just going to contemplate the sheer craftsmanship of this conspiracy theory. It's got all the requisite elements:

"Bush Stole the Election!(TM)" obligatory lead-in - check
"Whatever embarrasses us must be the other side's fault!" - check
"Republican dirty tricks!" - check

But wait a minute. They're sacrificing Al Sharpton for this! I guess he's expendable now. Next they'll be airbrushing him out of all the old photos.
