Former President Barack Obama will soon be fundraising for his former running mate and former Vice President Joe Biden who is set to challenge President Donald Trump in the upcoming 2020 election.

The Daily Wire reports: “Biden had an excellent May, raising an astounding $80 million — slightly more than Trump and the Republican National Committee raised in the same time period — but still lags far behind in overall cash on hand. The Trump war chest is well into the hundreds of millions and both Biden and the Democratic National Committee have ground to make up.”

Obama will host Biden’s first “offline” in-person fundraiser on Tuesday evening.

“The small-dollar fundraiser Tuesday night will be held online and offers a fresh test of Obama’s ability to transfer his popularity to Biden, his former vice president who is now seeking the White House on his own,” reported Politico on Tuesday. “It’s a kickoff of what Obama’s team says will likely be a busy schedule heading into the fall, as he looks to help elect not just Biden but Democrats running for House and Senate.”

Obama’s goal is to motivate his own voters who voted for him in 2008 and 2012 to come out and support Biden in the upcoming presidential election.

“There are two groups of voters that Biden needs to move,” said foremr White House communications director for Obama, Dan Pfeiffer. “You have the 4 million Obama 2012 voters that sat out in ’16, Obama obviously has cache with them. And you have to persuade some number of voters who voted for Barack Obama in 2012 and either Trump or a third-party candidate in 2016, and Obama obviously is very, very high-performing with those as well.”

Although Biden is currently leading President Trump in the polls, the American public is concerned about his mental decline.

According to a new Zogby poll, 55% of “likely voters” think that former Vice President and 2020 Democratic presidential candidate Joe Biden “is in the early stages of dementia.”

“Overall, subgroups who normally approve of Trump’s job as president, were the most likely to believe Biden could be suffering from dementia,” the poll found. “Thus, majorities of Republicans (77% more likely/23% less likely) and Independents (56% more likely/44% less likely) thought Joe Biden had early-onset dementia; while nearly a third of Democrats (32% more likely/68% less likely) thought this was the case.”

“At the same time, some important subgroups did not believe the vice president was exhibiting a declining mental capacity. While a majority of men (60% more likely/40% less likely) thought it this was likely, women (50% more likely/50% less likely) were less likely to think that the vice president was in the early stages of dementia,” Zogby International wrote.

They continue:

There was also an inverse relationship in the data between age and the likelihood of voters believing Biden had early-onset dementia, for example; as the age of voters increased the likelihood of voters believing Biden was exhibiting early-onset dementia decreased. Younger voters aged 18-24 (60% more likely/40% less likely) and 18-29 (59% more likely/41% less likely) were more likely to believe Biden had dementia than older voters aged 65+ (50% more likely/50% less likely).

Likely voters living in medium size cities (61% more likely/39% less likely) were more likely to believe Biden had dementia than voters living in the suburbs (52% more likely/48% less likely) and large cities (55% more likely/45% less likely). Suburban women (49% more likely/51% less likely) did not think Biden was mentally slipping but men living in urban areas (62% more likely/38% less likely) believed so.
