Here's how Max Boot puts the question in The Washington Post:
“Trump is on track to be the first president since World War II to see a net loss of jobs during his term. Even worse, he has presided over the loss of 214,000 lives and counting from covid-19. That’s already nearly four times the U.S. fatalities in the Vietnam War, previously the nadir of presidential bungling. Even now, after having contracted covid-19 himself, Trump refuses to take the pandemic seriously. He keeps promising it will magically disappear of its own accord while holding rallies practically guaranteed to spread the disease.”
“As if that weren’t reason enough to vote for Biden, there is also the fact that Trump has abused his power; he was even impeached for doing so. He has trafficked in racism and xenophobia. He has incited violence. He has kowtowed to dictators and trashed our alliances. He has welcomed Russian attacks on our elections. He has locked children in cages. He has called for his opponents to be locked up. In sum, Trump has made a strong case that he is the worst president in our history.”
“Yet tens of millions of voters still support him. What are they thinking?”
