I’m unfamiliar with what you are referring to: “what problems unsealed documents can cause”
More info, please.
Obama won his Senate race by having his opponent’s (Jack Ryan) divorce records unsealed. The divorce records showed that the opponent had taken his wife to some swingers clubs and the opponent pulled out of the race because of fear of the damage done to his 8 (ish) year old child.
His wife was the very pretty Jeri Ryan who played “Seven of Nine” in Star Trek Next Generation.
Obama was helped out considerably in 2004 when the media went after his primary opponent, Blair Hull, who was the frontrunner at the time. They uncovered a pretty sordid domestic situation involving abuse, drug use, etc. Then the media went after the GOP nominee, Jack Ryan, who had been married to a Hollywood actress, and sued to have his divorce records unsealed and made public. Ryan and his ex fought this and lost. The records exposed some kinkiness Ryan wanted his wife to indulge in at some club. That was one of the things that led to the divorce. After this, Ryan resigned the nomination, the GOP couldn’t find a replacement until Alan Keyes agreed to run — and Obama’s path to the Senate was guaranteed. I’ve always been suspicious about how that all worked out.
