Jen O'Malley Dillon, Joe Biden's campaign manager, warned followers against arrogance, pointing to questionable polls and lessons learned from Trump's amazing win in 2016.
"The reality is that this race is far closer than some of the punditry we’re seeing on Twitter and on TV would suggest," Dillon described in the memo that was published. Dillon advised that polling showing Biden ahead may not be true.
“Even the best polling can be wrong and that variables like turnout mean that in a number of critical swing states we are fundamentally tied," Dillon wrote.
The message to supporters was to push harder in the last couple of miles of the elections marathon to increase attendance and donations. "We need to campaign like we are trailing," the memo said.
“If we learned anything from 2016, it’s that we cannot underestimate Donald Trump or his ability to claw his way back into contention in the final days of a campaign, through whatever smears or underhanded tactics he has at his disposal," Dillon wrote.
Dillon's state-of-the-race memo described what's positive in the Biden campaign in the final days of the election, including Biden's financial advantage, nearly 3,500 staff working to organize in battleground states, and the "largest and best-resourced vote protection program in history."
She said while Biden's campaign has spent more than any presidential campaign in history on advertising, the benefits could be instantly washed off if more billionaires write checks to pro-Trump super PACs.
This was likely a citation to casino magnate and Republican mega donor Sheldon Adelson and his wife Miriam contributing $75 million last month to a super PAC backing Trump.
Over the next three weekends, like it was said in the memo, the campaign needs to "double our capacity" on voter outreach in 17 battleground states and raise $234 million by Nov. 3. If they surpass that amount, Biden can put more efforts in Texas, a traditionally red-leaning state that Democrats have been trying to overturn for many cycles.
The campaign also is preparing for potential problems at polling places and contested votes, with 17 state-specific voter hotlines and "thousands of lawyers and volunteers" working on voter protection.
“We cannot become complacent because the very searing truth is that Donald Trump can still win this race," Dillion wrote, "and every indication we have shows that this thing is going to come down to the wire."
