Well, duh. He was an incompetent boob. As I’ve long said, that case needed a seasoned prosecutor with RICO experience, not an amiable “distinguished” federal judge. While I can easily believe that Hillary was a bitch to her former lover, I remain skeptical that Vince Foster murdered Vince Foster; he was convicted without a proper trial or investigation.
I’m not sure I’d characterize the investigation as “failed,” though. It has (so far) accomplished what it was supposed to: Cover up the wrongdoing of 2016 (and before) and cripple the Trump presidency. Though the former is starting to unravel, I hope.
