I have two guesses.
Michelle Malkin was a featured speaker. She's pushing a new book that suggests President Obama is a corrupt politician bringing an atmosphere of corruption to politics in Washington D.C. She also seems to have an axe to grind against Michelle Obama, who she frequently singles out for criticism in her book and in her public comments.
It's pretty unusual for a political commentator to single out the First Lady of the United States for partisan attack, but it seems anything goes with this president. But it does beg the question:
What does Michelle have against Michelle?
One is envy of Michelle Obama's intellect, decorum, kindness and a good looking husband.
Michelle Malkin is just not a nice person, who would, let's say, spy on and belittle sick kids.
