It is fair to tag Republicans with spreading the "big lie" with respect to the Affordable Care Act, especially their hysterical claims regarding "death panels" (Politifact's 2009 Lie of the Year) and the "government takeover of health care" (Politifact's 2010 Lie of the Year).
And if Democratic Rep. Steve Cohen had left it at that, he would have been on solid ground. Instead, in a speech from the House floor last night, Rep. Cohen went on to equate the Republicans' lies with the Holocaust, saying "The Germans said enough about the Jews and people believed it--believed it and you have the Holocaust."
Rep. Cohen's slurs are reprehensible. He should retract them and apologize for them.
