USA Today reports:
Six months before Election Day, the coronavirus pandemic has done what impeachment did not: Cost President Donald Trump his advantage over Joe Biden in the 2020 campaign.
A new USA TODAY/Suffolk University Poll shows the former vice president leading Trump nationwide by six percentage points, 44%-38%, a shift from Trump’s three-point lead in the survey as he was being impeached by the House in December. In a contest without a third-party contender, Biden’s margin jumps to 10 points, 50%-40%.
In the previous poll, when Trump led 44%-41%, Biden was in the middle of a fierce battle for the Democratic nomination. Now he is the party’s presumptive nominee.
