Assuming the tape exists:
1) The RNC or a friendly 527 probably has the tape
2) The “rumors” on the internet are psych ops against Obama and his campaign (and the MSM as well)
3) The tape will not be released until Obama has locked up the nomination air tight (it seems he already has)
4) Hillary is not going to concede while there is a chance the tape could end Obama’s candidacy
5) If the tape is released sometime this summer then superdelegates will abandon Obama and rush to Hillary
6) Hillary will try to blame the tape’s release solely on the Repubs, thus trying to re-ingratiate herself with African American voters, Bill’s one time most loyal supporters
7) African American voters by and large will not buy the Clinton’s spin that they didn’t play any part in the tape’s release, there will be incredible anger in the African American community over the Obama campaign’s demise
8) Hillary attracts only 50% of the African American vote (at best) in the general
