Democrats running for president are determined to make the 2020 election a referendum on single-payer health care. My advice: Bring it on. This is a fight President Trump and the GOP should welcome.

But in order to win, the GOP has to come to terms with its past failures, reflect on its limited successes, and chart a new course. We have to boldly define what we are for, not just what we are against, and win the hearts and minds – and trust – of voters.
