The Anchoress has a good post on the recent announcement that Sacco and Vanzetti were guilty, and that Upton Sinclair hid his knowledge of their crimes in order to do his antediluvian Free Mumia!!!/Free Tookie!!! impersonation. The announcement of Sinclair's letter prompts Jonah Goldberg to add:

So which leftwing martyr/icon is left? Sacco & Vanzetti were guilty. The Rosenbergs: guilty. Hiss: guilty. Margaret Mead: liar. Rigoberta Menchu: liar. Duranty: liar. Kinsey: liar. Upton Sinclair: liar. I.F. Stone isn’t looking too hot (lied about America often, loved totalitarians, might have taken KGB money).

Martin Luther King Jr. — small flaws aside — is still looking good. But Bobby Kennedy is only a useful leftwing hero if you don’t look too closely. Ditto JFK. Jesse Jackson’s going to look awful to historians.

Who’s left?

But seriously, the Anchoress adds one more name to Jonah Goldberg's list:

There’s always John Kerry, greatest war hero, ever. Still waiting for the general, free release of those military records, aren’t we? Why yes, yes we are.
