Sealed records can always be unsealed for the right price. Obama had sealed records unsealed of opponents who probably would have defeated him in the Illinois senate race.
The main one was Rep. Paul Ryan of Illinois. Obama was actually losing in the polls and got a judge to unseal Ryan’s divorce records despite how it would have a devastating impact his children. The judge made the excuse that it was ok to do so since Ryan was a public figure. It was all over as Obama’s minions attacked Ryan and his wife’s sex lives.
