In our divided country, a reality that often goes unnoticed is that millions of Americans – of all political stripes – struggle to put food on the table. That’s where food pantries come in, providing a crucial lifeline. They’re there if a family needs them regularly, and they’re there if a family needs them just now and again to get through the month. And these pantries need help. That's where we, the divided masses, come in, writes @usatodayopinion columnist Rex Huppke. __________ I’ve teamed up with @feedingamerica, a national nonprofit that supplies about 200 food banks across the country, to launch the Insult-A-Columnist Holiday Food Drive. The concept is simple. You donate to Feeding America under one of two team names: RexRocks or RexStinks. No matter which team you choose, your contribution will be directed to a food bank near you, based on the ZIP code you provide. The food banks in the Feeding America network provide groceries to tens of millions of people nationwide through pantries, shelters and other community outreach organizations. It’s a way for all of us – regardless of politics or ideologies – to come together and do some good for our friends and neighbors who might be toeing that perilously thin line between making ends meet and being unable to afford enough food.
