"By the numbers"

[HighPopalorum]

I thought the Dept of Revenue was setting those numbers...

Those numbers are from the legislature's fiscal analysts. They are like the CBO, in that they calculate the economic impact of legislation in terms of costs and revenue in order to give lawmakers guidance, and provide the nuts-and-bolts details about where the money will come from and in what manner it will be used. The document the blogger drew them from is here.
