This is the Bush family trying to get back in the good graces of the liberal Establishment whose approval they crave so desperately. When Bush left office, he was Evil incarnate to the Left and a huge disappointment to the Right. He kept his mouth shut and his approval numbers started rising. Now the family sees it chance to slam Trump and earn points with the people who used to hate and ridicule him. The whole family has a repugnant combination of arrogant aloofness and battered wife syndrome.
Yes, since when does the Compost care what Mrs. Shrub/Mrs. Chimp/Mrs. Bushhitler thinks about anything?
