Election 2020 Poll: Biden Takes Post-Convention Leads Over Trump In Arizona, Georgia

Joe Biden increased his lead over President Donald Trump in five of 11 key battleground states in a major opinion poll taken after the Democratic and Republican national conventions while maintaining his lead in the remaining six.

The post-convention bounce that saw Trump's favorability rating rise only a few percentage points has seemingly disappeared. The latest Morning Consult poll released Tuesday shows Biden now leading Trump nationally by eight points, 51% to 43%, precisely the same result uncovered by the previous Morning Consult poll earlier this month. In contrast, Hillary Clinton held a three-point lead over Trump after the 2016 conventions.

Individual polls in these battleground states show Biden boosting his lead in Arizona, Georgia, Michigan, Ohio and Wisconsin. Biden held on to his lead (diminished in a few cases) in Colorado, Florida, Minnesota, North Carolina, Pennsylvania and Texas.

Trump post-convention major gains were in Pennsylvania, where he added two percentage points, and Florida where he added three percentage points. Trump remained behind Biden in both states, however.

In Wisconsin, currently the center of national attention due to the police shooting of African-American Jacob Blake, Biden boosted his lead by three percentage points to 52%. Trump saw his post-convention rating remain unchanged at 43%.

The poll appears to indicate Trump's strident law-and-order message warning of crime and chaos under a Biden presidency has failed to resonate with voters. Trump visited Kenosha, Wisc., on Tuesday to praise police for their work in the street protests in the wake of the Aug. 23 Blake shooting.

Biden posted his largest gain in Arizona, where his campaign has spent millions to flip the state Trump narrowly won in 2016. Biden's now ahead of Trump by 10 percentage points, 52% to 42%. Before the start of the conventions, Biden trailed Trump by two percentage points.

Morning Consult said the Biden did quite well among suburban Arizonans, whose support for him rose by nine percentage points, 51% to 42%. Biden also leads among women (55% to 40%) and Independents (51% to 37%) in the state.

Biden now leads Trump in the traditionally red state of Georgia, 49% to 46%, which is a four-percentage point gain over the previous survey where Trump led, 47% to 46%.

The new poll follow a brief Trump bump reflected in a Morning Consult poll released Aug. 29. It found Biden's national lead had fallen from six points from 10, and that Trump had gained support among white voters. Morning Consult later said this particular daily tracking poll reflected a "post-convention bump" that "proved to be fleeting."

"Similarly, movement away from Biden and toward Trump that was detected on Friday among white voters and suburbanites was short-lived, with the three-day survey showing no significant national shifts among those groups," said Morning Consult.
