Three polls released Wednesday show presumptive Democratic nominee Joe Biden with a solid lead on incumbent Donald Trump. 

Polls from Economist/YouGov and CNBC/Change Research both show Biden leading by 9 percentage points. Rasmussen Reports, a right-leaning polling company, shows Biden leading Trump, 48%-42%.

CNBC/Change Research surveys of battleground states painted a grim picture for Trump's reelection bid. Polling shows Biden owns slim leads in Arizona, Florida, Michigan, North Carolina, Pennsylvania and Wisconsin. Of the six states, Biden fares the best in Wisconsin, with a 5-point lead, and fares the worst in Arizona and Pennsylvania, where he has a 2-point lead. The six states have a total of 101 electoral votes. 

Since establishing a clear path to the Democratic nomination, Biden has consistently looked strong in most polls in head-to-head matchups with Trump.

On Monday, a Harvard CAPS-Harris Poll survey showed Biden leading Trump by 10 points. The national poll noted that Biden is viewed by a strong majority of voters as better equipped to lead during the coronavirus and racial turbulence.

An NBC News/Marist Poll released Monday showed Biden leading by 7 points in North Carolina, and also showed Democratic Senate candidate Cal Cunningham leading Sen. Thom Tillis by 9 points and Democratic Gov. Roy Cooper leading Republican challenger Dan Forest by 20 points. 

Biden is expected to name his running mate in the coming days. Among his top choices are California Sen. Kamala Harris, former Obama National Security Adviser Susan Rice and Illinois Sen. Tammy Duckworth. The pick could result in a shift in polling numbers, depending on the public response to the running mate choice.

Trump and Biden will have their first of three debates on Sept. 29 in Cleveland. The election, which will take place on Nov. 3, is 96 days away.
