@Nonilex The current court is more the working of Mitch McConnell than of Trump. McConnell withheld the confirmation of Merrick Garland, and this began before Trump had become a candidate. McConnell rushed the confirmation of Amy Barrett--in direct contradiction of his "principle" devised to prevent Garland from being confirmed.
Unrelated, but McConnell could have checked Trump at any point but refused to do so.
