Obama, Clinton, Comey. Lynch, and on down the line are all inoculated by Russia Collusion in an attempt to get Trump.
Election Security for Midterms and after is viewed differently. Russians may be thought to be involved in future elections but in terms of collusion in 2016 to influence the election against HRC, Sessions is locked out by his own recusal.
The Russia Collusion is confined to those activities that happened in 2016-2017 thought to suppress voter turnout in November 2016.
Sessions is recused from all of that.
Sessions as AG still has purview of Election Security from 2018 on. Whether he is competent or not is subject to opinion but the 2016-2017 schemes and coup attempts are not taken to him for action.
DHS is prime office for Election Security. DOJ is tasked to investigate, arrest, prosecute election law violators.
Do I personally have confidence in Sessions for his part of Election Security? No.
Will he accomplish some enforcement in matters of election security? He will accomplish some things but he will not have IMO a comprehensive handle on it.
