Donald J. Trump is having the time of his life as he taunts those who oppose his election as president of the United States.

He went on yet another Twitter rant with a message that belies his pledge to be the president “of all Americans.” Imagine that.

He wrote: “Happy New Year to all, including to my many enemies and those who have fought me and lost so badly they just don’t know what to do. Love!” 

There you go. Such grace. Such class. Such a striving to make good on his promise to “unify” a divided nation.

I guess this latest example strikes right at the heart — in my view — of this guy’s temperamental unfitness for the job to which he has been elected.

He blasts out these tweets, using the social medium to inject himself into the middle of foreign policy discussions being conducted by the individual who still is serving as president and commander in chief.

This latest lack of decorum only serves  to inflame the anger of those who need little reason to be angry that this guy won the election.

The unity you profess to seek, Mr. President-elect, cannot be found in these childish messages.
