The South Dakota Attorney General has announced there will be no charges of offering something of value in a plan on indian reservations to give away chili.  The Argus Leader:

“Republicans filed a formal complaint with Jackley after Democrats held early-vote chili feeds on three reservations in mid-October. They alleged that offering food in exchange to vote violated federal and state laws.”

This is a state level determination.  The Department of Justice could also look into federal charges of offering something of value to vote.
