DT said a lot of things that were false. Not only did he not do any "draining", he made the swamp swampier.
Yes, It seems that you're right. It looks like the crocodiles devoured him..... But I still believe that the primary reason that DT got elected was because most Americans recognize that Washington DC is a stinkin swamp ( And the denizens of DC are there to be near the vault that holds our tax dollars) And DT was elected because he said that he was going to drain that stinkin swamp...but it appears that the swamp was too big for him....
