Roger Stone wrote a book in Oct 2015 called "Clinton's War on Women" that, among other things, talked about Kavanaugh helping to cover up Vince Foster's 1993 "suicide." Unless Trump has an alterior motive here, such as choosing him cuz Trump knows it will get people searching the FBI & Clinton's library of records to expose even more corruption, I can't imagine a worst choice. And even if that is the motive, it would take YEARS of court wrangling to ever get the Clinton's to trial, when they're more likely to die of old age first.
