If you try to bake a cake, but after looking at a recipe you notice you made multiple mistakes in the batter, the best idea is usually to start over from scratch. If you used three eggs when the recipe called for two, a tablespoon of salt when the recipe called for a teaspoon and a chocolate mix but you find out a guest is allergic to chocolate, it is best to start over. Rather than try to pull an egg out of the batter, pick out the excess salt and sift the chocolate mix out, you should throw out the batter and make a batter that will actually work for the cake. This principle also applies to laws passed by Congress.
