"The poll underscores dissatisfaction with how Trump is managing his presidency -- even in six states that he won in 2016. The battlegrounds, which include coronavirus hot spots Arizona and Florida, will likely once again determine who wins the White House this year."Across the six swing states, voters seem to trust Biden more than Trump when it comes to key issues.
Fifty-four percent of respondents said that Biden would handle the COVID-19 pandemic better than Trump. Fifty-five percent said Biden and his fellow Democrats would do a better job of "making health care more affordable," while 53 percent said that the former vice president and his allies would put the middle class first.
Recent polling suggests that Biden has expanded his nationwide lead. The latest Quinnipiac University survey put Trump 15 percentage points behind the Democrat, establishing that the president has lost ground among Republicans and independents.
