I obviously vote to expand. (see sig)
The image in your sig is a little bit misleading, since the two sources are measuring somewhat differently - a family who pays only $36 in taxes for food stamps isn't going to be paying even $1000 in federal income tax total. Still, the point that corporate subsidies take up more money than food stamps stands.
In the current economy with unemployment the way it is, we shouldn't reduce food stamps. I'd be open to expanding it so long as we did more to make sure its targeted to the people who really need it and minimize fraud. Some of the reforms proposed lately by the House Republicans however are wrongheaded - a person should be able to put some money in savings to help them get back on their feet and still be eligible.
