Why allow a loose cannon to go around attacking the administration? It is far more likely to me that someone wanted to discredit the administration, and therefore blackmailed Ritter into attacking Bush in the media.
Especially because Ritter was VERY anti-Clinton in his testimony before Biden.
Anything anti-Demonkrat and Pro-Bush is automatically more likely to you. You're a partisan.
In reality, it's equally likely as the other possibilities I have outlined. Because we don't have enough evidence yet.
