Jon Corzine videotape scandal?

Enlighten New Jersey is posting rumors of a tape that may damage Senator Corzine's chances to be elected governor of New Jersey next month:

That's not the end of it. Reporters are after a videotape of Corzine, inebriated, making statements that will damage him beyond belief with African Americans. (Carla Katz supposedly makes an appearance.) People who have seen this thing say it's bad. African American leaders are aware of its existence, and don't think the damage can be undone no matter how many $2 million "contributions" he throws their way. The only question is whether we find out about this before he's governor, or after.

Yesterday evening, Enlighten New Jersey posted the following:
The next 48 hours could dramatically change the direction of this race.
I don't know if it is true and I have never visited Enlighten New Jersey before. It is worth investigating. If these allegations centered around Corzine's Republican opponent, there would already be a grand jury by now.
