I believe Miers has argued many cases in court. She is a litigator by profession, as I understand.
Ms. Miers had a distinguished career as a trial litigator, representing such clients as Microsoft, Walt Disney Co. and SunGard Data Systems Inc. Moreover, when she left her law firm of Locke, Liddell & Sapp, Ms. Miers was serving as Co-Managing Partner of the firm which had more than 400 lawyers.
Corporate law, never been on the bench, and was a demonrat in the '80s. She is definitely not the best athlete available.
