Not really, unless the block grant is written in a way that would allow this which is unlikely. It's not just here's money spend it how you want. It's here's money it has to be spent on a food assistance program. These conditions must be met etc etc etc.
So you think if they give block grants the money would be distributed the exact same way no matter who the governor/state representatives are? You can't tell me that they won't come up with ideas that favor people that are more likely to vote for them
So my my prediction comes true.
