Krugman is in the same business....he's an editorialist who makes inflammatory statements to sell papers. He consistently blames everything bad going on in the world today on Bush and the Republican party. There is absolutely nothing wrong with liking columnists and authors like this but to suggest that the ones who are biased towards your political leaning have some type of moral high ground while the ones that lean the other way are lower life forms is just, in my opinion, silly.
"But the vitriol also reflects the fact that many of the people at the Republican National Convention, for all their flag-waving, hate America. They want a controlled, monolithic society; they fear and loathe our nation's freedom, diversity and complexity."-Paul Krugman
"Can we break the machine that is imposing right-wing radicalism on the United States? The scariest part is that the media is part of that machine."-
Paul Krugman

All of these people are to some degree entertainers attempting to entertain likeminded folk with their opinions. Some are edgier than others but they're all making their money the same way....by reflecting back to us what we dislike about our political opponents. Some are wittier than others and some are way over the top so depending on your mood and preference you can find someone for you. Some people like
clean comics and some people get a kick out of Dave Chapelle, Chris Rock, or Howard Stern. Coulter is outrageous in a way that turns many off. Moore is similar though it's more subtle and passive aggressive. Others, like Krugman, attempt to walk the line while trying to remain credible but they are all in the same business.....entertaining us with their opinions.
