It seems that everywhere one turns, Congress, state legislators, and local elected officials are making “Grand Bargains.” So, what is a Grand Bargain?
A “bargain” is, generally speaking (in “dictionary” language), an agreement by one party to buy and another to sell. (There must also be “consideration,” but that is another topic of discussion.) See definitions in the Free Dictionary and in the free, online Merriam-Webster.
“Grand” means, simply speaking, large, in size or scope.
