Exactly. If Stumbo does not win the AG race, the Lundergan establishment will be completely out of power...for the first time in decades, as Grimes herself is term limited and Stumbo was ousted from the House (even as the incumbent Speaker) in the 2016 election.
I am not so sure about your last sentence, though...I believe the Beshears could have been instigators of that in order to damage Grimes as they are a rival faction of the Kentucky Democrat Party. I don’t know that...but I am far from the first or last person to find it an all too convenient coincidence on the timing of those prosecutions to push Grimes out of running for governor.
