They may be economic changes, but there's little the Fed can do by raising or lowering rates. People have to go to work, and they have to eat.
Back when inflation reared its ugly head, I was at my local mega grocery store looking at olive oils. There was a young couple talking, and I overheard them saying the prices of "fat" had gone way up. Their cart was filled with soups and other fairly low cost food that would fill them up.
And the costs of food and fuel are not going to get cheaper soon. There's little the govt can do even if Trump gets elected. Actually, it'd get worse, because we need more fuel sources (which he opposes) and we need farmers to grow more, with less fertilizer and more heat.
