"As we’ve seen for the last seven years, there aren’t many places conservatives won’t go when attacking Obama. From racist accusations that he isn’t an American citizen to a staggering number of threats against the president’s life keeping the Secret Service busy, it’s hard to think of a U.S. president who has had to endure more ugliness from people who disagree with him.
Michelle Obama, as First Lady, has also endured a sickening amount of vitriol hurled at her over the years. Because of her interest in keeping kids healthy and eating well, conservatives have taken to constantly attacking her body. Fox News, for example, can’t stop calling the First Lady fat in the most disgusting segments imaginable.
The attacks on the Obamas may be disgusting, but on a certain level they are understandable. Racists and the right-wing fringe hate what they represent, hate that they are in the White House, and – worst of all – hate that Obama has actually had a massively successful presidency. Being first and being great are two things that have historically led to intense backlash from the people who preferred the status quo."
