If the two major party candidates for president care about our nation’s food supply, they certainly aren’t doing much to indicate that.

About six months ago, The Huffington Post sent a list of eight questions concerning food and agricultural policy to all the Republican and Democratic campaigns. We received no responses.

Since then, of course, the field of contenders has winnowed to Democratic nominee Hillary Clinton and Republican nominee Donald Trump. But when it comes to what the candidates have said concerning hunger, nutrition, GMO labeling or sustainable agriculture, little has changed.

Celebrity chef Tom Colicchio says he thinks the candidates’ virtual silence on these issues is unacceptable, but it’s not surprising given the tone of the race.

“What’s going on right now [in the election] is not about policy at all. It’s only about optics at this point, which is really depressing,” Colicchio told HuffPost.

Nevertheless, Colicchio is pushing for food policy discussion to enter the fray. In his role as co-founder of the advocacy group Food Policy Action, the “Top Chef” judge spoke at rallies held in conjunction with both the Democratic and Republican National Conventions this summer.
