Mr. Winters observations are astute.  Significant achievements of President Obama are left out, however, both at home and broad.
The Paris Climate Accord brought American leadership to an issue of immense world importance.  With his efforts, especially with China, global awareness and action continues, and will without Trump.  He protected vast American lands and seas for posterity, and from damaging ecological development. Restriction of oil and gas development in our threatened ocean adds to his strong record. Overall, he was an effective advocate for the health of Mother Earth, and of our own. I see his work in the spirit of Pope Francis encyclical Si Laudate, and among his best.

I include his tireless work for peace between Israel and Palestine. While supporting Israel, he advocated for a people with little voice. He forged solid working relations with leaders in Europe, India and Asia. The image of Pres. Obama and Prime Minister Abe at Pearl Harbor is one I shall never forget.
