This obsession and obstinate insistence on holding Trump to a 2015 promise that he changed in 2016 is just ludicrous.  

It is inane and ludicrous to obstinately insist that Trump did not nor can not change his mind on any of his Election2016 promise.

Inane and ludicrous because, get this, Trump promised to place Clinton in jail in Election 2016 when he becomes president.
