That is why Iowa wanted to be the first primary state. To exert their influence over food policy.
I have felt for a long time that all states should have their primaries at the same time. Certain candidates are given unfair advantages if they do well in the primaries of the “early” states. A candidate could easily become discouraged if he doesn’t do well in the early primaries. Not sure if something on this order could be enforced or not, but to me, it would improve the election process.
