1996? Slick was running for re-election that year and used DOMA to keep up the pretense of being some sort of centrist, and to keep fooling the so-called moderates, among other less than honest reasons.
obama has shown the Clintons it’s possible to be liberal and be president. So, they turned from their phony centrist ways to the left. And Bill wants to be the first “first husband”. Plus, as FHOTUS he can get in on in the Oval office while Hillary is away. He loves gettin’ in on in the Oval office. That room will draw the “flies” like honey.
