In the first place Bill Clinton was only bared from practicing law in Arkansas. He was not bared from practicing in any federal court.
And his baring in Arkansas was only for a period of some 5 years, which expired in 2006. Indeed he would have to apply to have his license reinstated (and I do not know if he has done this), but I seriously doubt if he needs to do that, as his book sales reimbursements and speaking fees are very high. He certainly does NOT have to practice law in order to be very wealthy.
And as for Hillery (the subject of this debate) she has never been bared from practicing anything she wishes to, up to and including being the President of the US!!
