Insanity.

You may not like Kamala, but voting for Trump is cutting your nose off to spite your face.

A lot of voters prefer Trump's position (if not his ability to implement policy) on immigration, border controls, and trade. They also generally think he's better suited on most economic matters, largely because his Administration coincided with a period of solid GDP growth, job growth, low inflation, and low interest rates until the pandemic began. They generally like his "speak loudly and wave your stick around a lot" approach to foreign policy as well.

Joe Biden sowed the seeds for losing this election when he and his economic team threw in with "Team Transitory" back in 2021. Regardless of whether they were right on the macroeconomic aspects of inflation (and Krugman would argue they were), it was tone-deaf and politically poisonous for the Administration not to realize how much the voters: i) hated inflation; and ii) would blame the Administration for it. Rebranding the Build Back Better Act as the Inflation Reduction Act didn't do anything to undo that political self-wound - if anything, it only made sure that Greens would be disappointed in the Administration.

Sometimes you fire the coach, because you can't fire the players. Harris is in that spot right now.
