More than most politicians, McCain was not simply a collection of policy positions. Although a true conservative, he could transgress Republican orthodox.
McCain will be remembered, above all, for his character and courage. While other privileged young men were discovering ailments such as "bone spurs" to avoid the Vietnam War, McCain requested a combat assignment and spent more than five hellish years in the "Hanoi Hilton" POW camp. Years later, he displayed characteristic largess of spirit by advocating reconciliation with his torturers.
McCain's dedication to America's global leadership, advocacy for human rights, steadfast opposition to despots, devotion to bipartisanship, willingness to break with his own party, insistence on putting the nation's interest above self-interest, and, above all, his unwavering sense of right and wrong - all are desperately needed at a time when his party has embraced an amoral, narcissistic demagogue who fawns over tyrants and flirts with isolationism and protectionism and white nationalism.
Trump hated McCain and insulted him at every turn because McCain was everything Trump is not - and everything we need in our politics but tragically lack.
