Somehow I missed this, but Obama's proposed Department of Health and Human Services budget would provide money to states to pass through more child support payments directly to families: Many states take a big hunk off enforced child support payments to recoup the cost of enforcement. It's a draconian practice that is especially hard on low-income fathers and mothers. Fathers with low-paying jobs struggle to make the payments, and less of it goes to their children. That is, after all, against the whole point of child support.
But Obama has expressed support for child support reform before. His budget is just an expression of his greatest budget desire, and it's hard to see increased aid to states in any form coming from a House of Representatives that wants to cut everything. Cut everything except, of course, benefits to the wealthy.
