Because he's such a mainstream superstar? If he's on your radar, it's most likely because you follow conservative websites and I'm assuming he's become a presence on them. Every time I see his name pop up here, I have to try to figure out what case he's affiliated with, then I look at the username and remember it's probably the biweekly Princess L update.
He has been covered on CNN, Young Turks, MSNBC...
Huffington Post, Mother Jones, Slate...
Insert any left wing site and add his name into google and at least a dozen entries will likely show up.
Why the need to be so disingenuous?
The man is all over the internet and television.
