First, “This president has always wanted the election to be about him. And, in these final hours he’s made sure to put the focus back on himself,” writes Amy Walter of The Cook Political Report, in a good state-of-the-midterms piece. Yet that approach may be a gift to Democrats, she explains: Trump’s approval ratings tend to rise when the focus is elsewhere — and fall when it’s on him.

Race, class or both? Since 2016, there has been a raging debate about the main causes of Donald Trump’s shocking victory. On one side are journalists, political scientists and others who believe that racial resentment was the overwhelming reason that Trump won. On the other side are people (including me) who believe this story is too simplistic and that, while race played a big role, economic factors did too.

In a new book, Steven Pearlstein of The Washington Post has a chart that reminds me of this debate. The chart contains two lines, the first measuring income inequality and the second measuring political polarization between the two parties in Congress. Both start in 1967 and go until almost the present. And both lines rise sharply, in close proximity: As inequality increases, so does polarization.
