Imagine there's no math

it isn't hard to do:

Imagine if the mayor of your nearest big city were to hold a press conference with the General Manager of the city’s Major League Baseball team. The Mayor announces that the GM, working with the coaches and players, has committed that he will work to develop plans for the team to hit the Mayor’s new goal of winning 40 more games this season than they otherwise would have won. Those plans will improve the team’s hitting, pitching, and fielding. The Mayor also announces that the manager’s plans, combined with the Mayor’s new policy initiative for better parking at the stadium, will make fans happier and help the team win more games.
...
The President is attempting to claim credit for [healthcare] savings that (a) do not yet exist, (b) are not backed up by any specific changes in industry practices or government policies, and (c) are related to him only in that the groups announced they were adopting his quantitative goal. For all three of these reasons, the President’s claim that these savings will materialize is wildly unrealistic, and it is absurd to attach a per-family savings number to it. This is like the Mayor claiming credit for the 40 additional wins now, and telling fans that he will be responsible for the team winning the pennant. No one should take these claims seriously.
