Years ago, I did a radio interview in which a member of the Detroit Free Press editorial board argued that people like Robert Byrd and Bill Clinton had basically earned the free passes they'd been given by the left. It seems that - after their horrible transgressions - they'd "voted to support" the issues liberals supported, and that was more important than who they may have raped, assaulted, or the years they spent recruiting for the Ku Klux Klan. To this day, I view that interview as the most succinct summation of the Democrat mentality that I've ever witnessed.
It was a variation of the "it was just sex," "personal lives don't matter," and "it was a long time ago" arguments that became the left's go-to in the 90's. It was also an admission that progressive platitudes are just that. If politicians vote in support of the oh-so-serious causes in which liberals believe, pretty much anything goes.
