Yesterday was the Iowa caucus; that has been overdiscussed and well nigh ridden to death as a topic. A recurrent complaint is that Iowa is not representative of the United States but has a disproportionate amount of clout in the selection of Presidential candidates. Yes, Iowa is a relatively homogeneous state, with particular issues and axes to grind that is not representative of the nation as a whole. Yes, the rest of us may not be as hot for ethanol as the Iowans happen to be; and Iowa does not have the racial or ethnic diversity as some other places.
The same with New Hampshire; maybe even in spades.
But what state is a microcosm of the nation? Even New York, California, Texas, or Florida fall short on a number of conceivable dimensions. I certainly can't claim Alabama or Tennessee as a true microcosm. Even whole regions fall short of the Platonic ideal of the microcosm.
Maybe the best thing is to declare a moratorium on this topic. Or, even better, have regions of states hold their primaries at the same time. If six or eight states are having their primaries on the same Tuesday in March or April or May, this spreads the clout joy around. But, better than that, it would shorten the effective election season.
The scope of media coverage has pretty well put pay to the need for candidates to appear in as many local communities as possible. Why do we still do the Presidential selection process this way?
And the political debates as they tend to occur nowadays result in a lot of posturing and grandstanding. We're likely to see more Trumps with the same situation in place in the future.
