The contempt that Hillary Clinton and Donald Trump express for each other will continue to play out in vitriolic sound bites. But their profound differences on what to do about the economy and the struggling middle class are far more important.
"This election will be won by whichever candidate convinces middle-class voters they are better for their jobs and future prospects," says Stephen Moore, a Heritage Foundation economist and Trump adviser.
"This is about whether economic forces hollow out the middle class or whether those forces strengthen the middle class, creating jobs and higher wages," says Gene Sperling, a leading economic official under Presidents Bill Clinton and Barack Obama, and an adviser to Hillary Clinton.
As the economy has recovered from the economic crisis, the unemployment rate has shrunk to less than half of what it was eight years ago and wages have started to rise. But medium average family income, in real dollars, is less than it was 10 years ago.
