I fail to see the appeal for Castle of being a Senator for 5 minutes or how Castle’s resignation could have been enforced, other than by offering a meaningful cabinet position.
Why not let some Biden family (d)og like then incumbent Kaufman be a stand in for Beau?
Fact is Beau would have run if he wasn’t scared of a competitive election with Castle, not enough people give a damn about nepotism, Princess Lisa is still in office.
It wasn’t an issue of being scared, but an issue of nepotism and the wrong time to run. He could wait a bit to get the seat, that was the plan. But he was going to get the seat. Plugs Senior was grooming his son for the Presidency.
