Wisconsin Democrats and the Democratic attorney general of Michigan are urging voters to return absentee ballots to election clerks’ offices or drop boxes, warning that the USPS may not be able to deliver ballots by the Election Day deadline.

Driving the news: The Supreme Court rejected an effort by Wisconsin Democrats and civil rights groups to extend the state's deadline for counting absentee ballots to six days after Election Day, as long as they were postmarked by Nov. 3. In Michigan, absentee ballots must also be received by 8 p.m. on Election Day in order to be counted.

Former President Barack Obama launched a blistering attack on President Trump while campaigning for Joe Biden in Orlando on Tuesday, criticizing Trump for complaining about the pandemic as cases soar and joking that he's "jealous of COVID's media coverage."

Driving the news: Trump has baselessly accused the news media of only focusing on covering the coronavirus pandemic — which has killed over 226,000 Americans so far and is surging across the country once again — as a way to deter people from voting on Election Day and distract from other issues.

A new Facebook campaign by a political arm of the Congressional Asian Pacific American Caucus identifies the Republican lawmakers who voted against a resolution in September denouncing anti-Asian racism, NBC News reports.

Why it matters: A number of Republicans, including President Trump, have repeatedly used racist rhetoric like “China plague” and “kung flu” to refer to the coronavirus. Research shows that anti-Asian bias rose 800% after terms like "Chinese virus" rose to prominence in conservative media in March.

Twenty Republican former U.S. attorneys on Tuesday endorsed Joe Biden while saying that "President Trump's leadership is a threat to the rule of law" in the U.S., the Washington Post reports.

What they're saying: In the letter, the former prosecutors criticize Trump's use of the Department of Justice, saying the president expects the DOJ "to serve his personal and political interests."

• "He has politicized the Justice Department, dictating its priorities along political lines and breaking down the barrier that prior administrations had maintained between political and prosecutorial decision making," the letter says.

Michigan Governor Gretchen Whitmer (D) said Tuesday that Trump's pursuit of reelection "is sowing division and putting leaders, especially women leaders, at risk." in an op-ed for The Atlantic.

Background: Whitmer, who faced criticism for her strict response to the pandemic, was the target of a violent kidnapping plot by members of extremist groups earlier this month. That has not stopped Trump from criticizing Whitmer at his rallies and calling her a "dictator" on Fox News.

Tech platforms are no longer satisfied with debunking falsehoods — now they're starting to invest in efforts that preemptively show users accurate information to help them counter falsehoods later on.

Why it matters: Experts argue that pre-bunking can be a more effective strategy for combating misinformation than fact-checking. It's also a less polarizing way to address misinformation than trying to apply judgements to posts after they've been shared.

President Trump is pouring hundreds of thousands of dollars into Facebook ads on the Supreme Court and conservative judges in the final stretch of his campaign, while Joe Biden is spending over a million on voter mobilization, according to an analysis by Axios using data from Bully Pulpit Interactive.

The big picture: Trump's Facebook ad messaging has fluctuated dramatically in conjunction with the news cycle throughout his campaign, while Biden's messaging has been much more consistent, focusing primarily on health care and the economy.

Mike Bloomberg is ploughing an additional $20 million into this election cycle, flooding the airwaves in North Carolina, Texas and Arizona to promote down-ballot candidates who share his views on climate.

The big picture: Bloomberg's last-minute cash infusion comes on top of the $100 million he pledged last month to help Joe Biden win Florida.

In her three decades in science, Jennifer Doudna said she has seen a gradual erosion of trust in the profession, but the recent Nobel Prize winner told "Axios on HBO" that the institution itself has been under assault from the current administration.

• "I think science is on the ballot," Doudna said in the interview.

Why it matters: That has manifested itself in everything from how the federal government approaches climate change to the pandemic.

Rep. Ilhan Omar told "Axios on HBO" that given the way progressives have shaped Joe Biden's policy platform, she and other members of "The Squad" expect a liberal turn from him if he's elected.

Why it matters: Progressives have largely refrained from publicly criticizing Biden in the lead-up to the election, even though he hasn't signed on to their most far-reaching policies. Instead, they're focusing solely on beating Trump.
