Actually, he is not wrong (technically). The bill specifically states income below 200% of the poverty line. You can read it at the library of congress:

If you add the amount for each child allowed to the standard and figure 200% above that, you will eventually reach 83,000/yr. :o)

>>And here's my favorite: "This program expands coverage, federal coverage, up to families earning $83,000 a year. That doesn't sound poor to me." But the bill he vetoed prohibits states from using the program to aid families who make more than three times the federal poverty limit, or about $60,000 a year for a family of four. Most of the aid would go to families earning substantially less.

>>Bush's spurious $83,000 figure comes from a request by New York state to use the program for some families earning four times the poverty limit. That request was denied by the Bush administration last month -- and that upper limit is not in the bill Bush vetoed. End of story. If New York or any other state were to ask again to be able to raise the income limits, the administration could simply say no.
