From the Alliance for Justice report (pdf):

Kavanaugh has less legal experience than nearly every past nominee to the D.C. Circuit, often described as the second most important in the country. When first nominated in 2003, Kavanaugh had been a lawyer for less than thirteen years and had little courtroom or litigation experience. Of the 54 judges appointed to the D.C. Circuit since Congress created it in 1893, only one, Kavanaugh's mentor Kenneth Starr, had fewer years of experience than Kavanaugh. Even now that Kavanaugh has been a lawyer for more than fourteen years--albeit in a non-legal position since his nomination--only three D.C. Circuit judges had less experience at the time of their appointments: Starr, failed Supreme Court nominee Douglas Ginsburg, and turn-of-thecentury jurist Charles Henry Robb.

John Kerry in a blog post today calls him Judge Brownie.
