My understanding is that Loretta Lynch is no Eric Holder.
Eric Holder was a radical first, who took part in the violent occupation of buildings while a student in Columbia University.
Lynch is less ideological, more of an ambitious climber, who leverages her Democrat Party connections to advance. She spent a lot of time as a prosecutor. Although the Party could call on her to handle cases they wanted prosecuted, she was relatively professional in handling other cases. She had a pretty positive reputation among FBI Agents who had worked in her district, when she went to her confirmation hearings.
She is much less likely to stick her neck out with a brazen abuse of office than Holder would be.
