Eugene McCarthy, R.I.P.
His anti-war insurgency pushed Johnson out of the White House, which drew Bobby Kennedy into the race, and his assassination crushed many people at that critical moment.
His ability to mobilize people who were dropping out of society in protest leaves a powerful lesson about the power of politics to draw people together, rather than pushing them apart.
There's some sort of analogy to be built with 2004, starring Howard Dean as Clean Gene, John Kerry as Humphrey, and no one really filling Bobby Kennedy's shoes.
Anyway, there are worse ways to be remembered that as the man who was right about Vietnam and who nearly healed the nation's rift.
