One of the huge successes of the left has been to rewrite history to the point of Nazi's being right wing.
The truth is they were nationalists, but they were national socialists.
In the history of the world since 1900. It has been socialist/communist's governments that have slaughtered their own citizens. This has never happened under a democratically elected political system.
This add correctly identifies Kerry/gore/kennedy/howard as being in the mold of Hitler.
Kerry doesn't demagog too well he is too monosylabic and unenergized but he does have a Marxist Poet as the soul of his camapign.
