Others say there’s little public appetite in a slash-and-burn campaign at a time when Americans are suffering. Former House Speaker Newt Gingrich, a Trump adviser and ally, said the president should wait until the late August convention to begin a full-fledged campaign and instead focus on dealing with the crisis.

Dealing with it effectively, he contended, would virtually cement Trump’s reelection.

“His best strategy is to follow FDR’s example and be Dr. Defeat the Virus and then Dr. Create Jobs and Prosperity,” Gingrich said.

Yet campaign officials see reason to begin nuking Biden, especially as the former vice president ramps up his attacks. Liberal outside groups have spent millions of dollars on TV ads in battleground states going after Trump. The former vice president’s campaign, meanwhile, recently released a web video charging that Trump left the country “unprepared and unprotected” — a spot that even some Republicans acknowledged was effective.
