WASHINGTON (AP) — Six months from Election Day, President Donald Trump’s prospects for winning a second term have been jolted by a historic pandemic and a cratering economy, rattling some of his Republican allies and upending the playbook his campaign had hoped to be using by now against Democrat Joe Biden. Trump’s standing has slumped as the nation’s focus on him has intensified during the coronavirus outbreak, revealing an erratic and often self-absorbed approach to the crisis. The result: He’s losing ground in some battleground states with key constituencies, including senior citizens and college-educated men — all without his Democratic challenger having devoted much energy or money to denting the president. For some Republicans, the prospect of an election that is almost wholly a referendum on Trump is unnerving. Though the president’s base remains loyal, a significant portion of GOP voters view him skeptically on a range of personal qualities. He pulled many of those voters to his side in the 2016 election by drawing an aggressive contrast with Democrat Hillary Clinton. He planned to do the same in 2020 with Biden, with the added tailwind of a surging American economy. Now, that economy is crumbling around Trump. A staggering 30 million Americans have lost their jobs in the past six weeks as businesses have shuttered due to stay-at-home restrictions aimed at containing the pandemic. One of the president’s own economic advisers predicted nationwide unemployment could reach 20% by June.
