Another option is to focus on specific issues that voters care about and where Democrats might have an edge, most notably health care. It sure seemed to work in the 2018 congressional midterms. But Democrats are blowing it this time around. Rather than push for an expansion of ObamaCare — which Americans favor 52 percent to 41 percent — leading candidates such as Bernie Sanders and Elizabeth Warren have pushed “Medicare-for-all.” But the more people hear about the idea — the fiscal cost, the elimination of private health insurance, the lost health-care jobs — the less they seem to like it. A new Quinnipiac poll finds “Medicare-for-all has grown increasingly unpopular among all American voters, as 36 percent say it is a good idea and 52 percent say it is a bad idea.” And while frontrunner Joe Biden supports adding a public option to ObamaCare, Trump can easily argue that the real Democratic goal is eventually getting to Medicare-for-all.

Maybe the best tact is to simply argue that Trump shouldn’t get much credit for the boomlet. After all, the decent economic news looks like a steady continuation of trends begun during the Obama presidency. And any good the Trump tax cuts might have done may have been offset by the Trump trade war. So what did Trumponomics do, exactly? Yet voters still have a tendency to credit presidents for the good that happens on their watch, although not as much as they used to. Hoping voters simply ignore their pocketbooks and 401ks isn’t much of a Plan C.
