Election 2020 Poll: Biden Leads Trump By 10 Points Nationally, 3 Points In Battlground States

More voters in Arizona, Florida, Michigan, North Carolina, Pennsylvania and Wisconsin -- the swing states some pundits say will determine who wins the presidency in November -- are throwing in their lot with Joe Biden, the Democratic Party's presumptive presidential candidate.

A new poll by CNBC/Change Research released Wednesday found Biden had boosted his lead over Trump in these swing states where Trump won in 2016. It's the first time Biden has led Trump in all six states.

The poll taken from June 12 to 14 and involving 2,408 likely voters show Biden’s lead over Trump growing significantly over the past two weeks in both the national and the battleground surveys. On the national level, the poll revealed Biden with a huge 10 point lead over Trump (51% to 41%). Change Research said this is a three point improvement since their previous poll two weeks ago.

Biden is also ahead of Trump by three points in battleground states (48% to 45%). He only held a one percentage point lead over Trump in the last swing-state poll released two weeks ago. Previous to Wednesday's results, Trump led Biden in all previous swing state polls extending back to March.

In the swing states, majorities disapprove of Trump’s overall job performance (53% disapprove, 50% strongly disapprove). More ominously for Trump, voter disapproval of his handling of the COVID-19 pandemic is at a new 55% high, up from 52% two weeks ago.

The swing state picture shows Biden atop Trump:

• Arizona: 45% to 44%
• Florida: 50% to 43%
• Michigan: 47% to 45%
• North Carolina: 47% to 45%
• Pennsylvania: 49% to 46%
• Wisconsin: 48% to 44%

Majorities give Trump negative marks for his handling of every other key issue measured in the poll (such as COVID-19 and police brutality), indicating widespread and widening voter discontent with Trump.

The poll found 55% of respondents in the six states disapprove of how Trump is handling the COVID-19 pandemic compared to 45% who approve. On police brutality and discrimination, 56% disapprove of the job Trump is doing, while 44% approve.

A full 52% of respondents said Trump’s response to the killing of George Floyd by a Minneapolis cop and protests for criminal justice reform are harmful. Only 23% say it's helpful.

The poll results also confirm voters increasingly prefer Biden and the Democrats to Trump and the Republicans when it comes to handling key issues. Voters believe Trump does a better job compared to Biden on only one issue -- getting people back to work (52%).
