In this article the excellent Tom Edsall speculates that rapid and recent job growth in Republican-leaning states may boost the president's chances for re-election.

But the job growth in the 20 or so states certain to return Republican pluralities is irrelevant.

All that matters with the crazy system by which the United States chooses presidents is the situation in Florida, Pennsylvania, Michigan, Wisconsin, and Minnesota. 

Of course it is true that job growth and wage growth—particularly among volatile segments, such as less educated people ages 22 to 60—has a huge impact on whether they vote and how they vote. But this consideration affects the outcome only as it applies to the handful of swing states.

If the United States used the national popular vote to pick the president, then the selection of the president would not turn on the fact that swing states by chance are located in a region of the country that lags in an economic recovery.

Should a poorly performing region have the tremendous clout that comes from picking the president?

There are three reasons the answer is no.

First, it is a mere accident that the few swing states currently are in the lagging Midwest. Suppose most people were suffering a sluggish economic recovery, but the swing states happened to be the booming Southwest. Then the well-off would be picking the president, leaving most people relatively ignored by the chief executive. The random selection of some states as swing states should not be the factor that causes the denizens of those states to get attention from candidates for president. 

Second, there are enough people in the Midwest—70 million!—to make it crucial in deciding who wins the national popular vote. Having a decisive role in the electoral college is not necessary for attention to be paid to the citizens of that region. It would be impossible for anyone seeking a national popular vote victory to ignore the Midwest, or to win without doing reasonably well in getting votes there. 

Third, many millions of Americans are underpaid or underemployed because they are less educated than necessary in the modern economy. They deserve to be treated as a voting block critical to choosing the president, regardless of where they live. Very affordable education, personal savings along the lines of Cory Booker's baby bonds, and very cheap health care costs are very important policies for all in this segment. But the focus only on this segment's representation in certain states tilts political promises toward hiring by local companies or hostility toward inbound migration, neither of which is as useful to address the fundamental problem.
