Million Mom Math uses a multiplier in all it's calculations, which increases exponentially as the input values increase.
For example, the MMM gathered a crowd of 75,000 on the mall in DC last year, but after puting this figure through the MMM calculator, the officially reported attendance was listed at 750,000. Numbers in the tens of thousands are calculated using a multiplier of 10.
To arive at the 35,000,000 member figure, one takes the actual membership of 350,000 and plugs it into the MMM calculator which increases the multiplier to 100 since our input value is now a figure in the hundreds of thousands, and we get a stated membership of 35,000,000.
Imagine if the NRA coiuld get their hands on one of these MMM calculators. I shudder to think of the suicidal carnage it would cause among gun grabbers.
