My mother once told me: Never assume mendacity when stupidity is a sufficient explanation for someone's behavior. This adage is being put to the test by Senate Republicans' fourth and final bill to repeal ObamaCare. Written by Sen. Lindsey Graham (R-S.C.) and Sen. Bill Cassidy (R-La.), this bill is so bad that you'd either have to be lying through your teeth or dumber than bricks to support it.
