Eric Holder took politicizing the office of AG to a whole new level, when he used it as a tool for his racism. That precedent will make it easier for future AGs to use the office to harass Christians.
This episode makes me wonder what political situation forced him into being another one of Obama's ritual sacrifices.
He wanted to resign before the election that's just over a month away, in case Republicans made gains in the Senate. The Senate has to approve the new AG. A new AG, someone other than Holder, would have better chance of being held over by Obama's replacement. I think Hillary would want to replace Holder. So, it's better for him to go now, on his own terms, than later. And, he probably has a nice-paying job lined up. Maybe giving six-figure speeches to well-heeled black and Democrat groups.
