Kaplan Kratovil Confused

I understand the difficulty of achieving Ballance under deadline preassure, but I think that Lori Montgomery and Shailagh Murray need some copy editing. They wrote

Kratovil said the bill is better than it was in July, but it still costs too much and would impose too heavy a burden on small businesses, many of which would be required for the first time to offer health insurance to their workers or face a stiff fine.

Note the last clause asserts, with the authority of the Washington Post, that the employer mandate would apply to many small firms. Thus they assert that many firms with payrolls over $500,000 are small firms. They do not make it clear that they are using this unusual definition of small firms. In fact, they give no real information on the employer mandate at all in their article in which they definitely assert that it applies to many small firms. A bit of googling lead me to this

", many of which " should be edited to ". He said many of which" or ", many of which, he said," if they have a shortage of periods. As is they switched from Kravotil's claim to one of their own without considering the fact of the matter.

Employer Mandate Excise Tax (Page 275): If an employer does not pay 72.5 percent of a single employee’s health premium (65 percent of a family employee), the employer must pay an excise tax equal to 8 percent of average wages. Small employers (measured by payroll size) have smaller payroll tax rates of 0 percent (<$500,000), 2 percent ($500,000-$585,000), 4 percent ($585,000-$670,000), and 6 percent ($670,000-$750,000).

Why is leftcoastrebel so much more informative than the Washingon Post ?
