Of course, in reality, it's also been anti-Obama forces like the LaRouche PAC who are actually and currently depicting OBAMA with a Hitler mustache on signs in Naugatuck (and elsewhere in the past) that they have been using since 2009. Other anonymous groups are circulating flyers depicting Obama as Hitler and indicating that the "the Holocaust is coming" in Michigan.

These do not appear to have anything to do with the Romney campaign, just like the one mention I can find of a Romney Hitler depiction in California likely has nothing to do with the Obama campaign.

Regardless of politics, those involved, including this cartoonist, should be ashamed at playing into such ugliness.
