Kirkland & Ellis, the firm famous for its Republican connections, must not be so Republican after all. At least not its Chicago office...
According to wiki, Kirkland & Ellis LLP gives 77% to Democrats and 97% in the 2008 Presidential cycle.
K & E has probably 1000+ lawyers — all over the country — a lot in DC — so it’s not amazing that out of all those people 150K came in (that’s a max from only 75 or so)
