There are a lot of lawyers to be sure, but fewer than I expected.
For the record, there are 435 Representatives and 100 Senators in Congress.
From Wikipedia:
The Congressional Research Service notes that the vast majority of Members (95 percent) had an academic degree:
168 Representatives and 57 Senators have a law degree. Of these, five (Representative and two Senators) also hold a Master of Laws (LL.M.) degree.
83 Representatives and 16 Senators earned a master's degree -- often a Master of Business Administration (M.B.A.) - as their highest educational degree
27 Representatives and one Senator (Mark Begich) have no educational degree beyond a high school diploma.
23 Representatives (but no Senators) have a Ph.D
17 Representatives and three Senators have a medical degree (this number includes one Senator with a veterinary medicine degree and one Representative with a dental degree).
Five Representatives (but no Senators) have an associate's degree as their highest degree. One House Member has a licensed practical nurse (L.P.N.) degree
