One obituary of many on the passing of John McCain: https://www.washingtonpost.com/local/obituaries/john-mccain-maverick-of-the-senate-and-former-pow-dies-at-81/2018/08/25/d9219b7e-a7b8-11e8-97ce-cc9042272f07_story.html
And my friend Jed Babbin sums up McCain well in this piece for the American Spectator: https://spectator.org/john-mccain-war-hero-conservative-apostate/
My short take on the departure of John McCain from this life: I never questioned John McCain's motivation, patriotism and determination. I did from time to time question his judgment and his faithfulness to the Constitution. I only met him once, and I challenged him about McCain-Feingold; he did not seem to enjoy my question. I appreciate his service to the nation, especially in the Navy. As for his political impact, I suppose his passing leaves me more sad for his friends and family than for the country. It's not that John McCain was a bad senator; there were and are many worse and many who love their country less. It's just that I would have hoped for better from the man whose seat was previously held by Barry Goldwater. As always, John McCain was a complicated man.
Senator John McCain's comments in 2017 when receiving the Liberty Medal are a good summary of the best parts of the man. The substance of the remarks starts around 3:30.
While I was never a big fan of John McCain, I do feel a bit sad that so many people will remember this as a defining moment of his career:

….And I’ve lost one of my dearest friends and mentor.
Words cannot express the sorrow I feel at John McCain’s passing. The world has lost a hero and a statesman. Cindy and the McCain family have lost a loving husband and father. I have lost a wonderful friend.— Jeff Flake (@JeffFlake) August 26, 2018
