Sen. Bernie Sanders has received $10 million from 359,914 donors since launching his 2020 presidential bid last week Tuesday, campaign officials told the New York Times in a report Monday, cementing him as the financial front-runner in an increasingly crowded Democratic field.

The details: Officials reportedly said almost 39% of the donors have used email addresses that weren't previously given to the Sanders campaign — suggesting that the senator is expanding the donor network for his second White House bid (though some may have updated their contact information). In the first 24 hours of his announcement, the campaign had said Sanders raised $5.9 million from 225,000 individuals donors.

By the numbers, per the Times:

  • The average contribution was under $26.
  • As of Monday, 20 gave the Sanders the legal maximum of $2,800; 46 gave $2,700, the limit in the 2016 campaign.
  • 48,000 have signed to make recurring donations from their credit cards
  • More than 108,000 of the first day donors were 39 years old and younger, giving $2.5 million of the $5.9 million raised.
  • $3 million on the first day came directly from mobile devices

Former Pennsylvania Gov. Tom Ridge announced in an op-ed Sunday that he would be voting for Joe Biden.

Why it matters: Ridge, who was also the first secretary of homeland security under George W. Bush, joins other prominent Republicans who have publicly said they will either not vote for Trump's re-election this November or will back Biden.

Tom Ridge, the former Republican governor of Pennsylvania, will vote for Joe Biden, he announced in a Philadelphia Inquirer op-ed on Sunday.

Why it matters: Ridge, who also served as the first Secretary of Homeland Security under George W. Bush, said this would be his first time casting a vote for a Democratic candidate for president. He's now the third former Republican governor from a swing state to endorse Biden and reject Trump — joining John Kasich from Ohio and Rick Snyder from Michigan.

Poll: Majority of voters say election winner should fill SCOTUS vacancy

A majority of voters believe the winner of the next election should fill the Supreme Court vacancy left by the death of Ruth Bader Ginsburg, a new poll from the New York Times and Siena College finds.

Why it matters: President Trump and Senate Republicans have vowed to swiftly confirm his nominee Amy Coney Barrett, in part hoping for a political boost as the conservative base is extremely motivated by issues concerning the court. The poll indicates that moving fast may not help them with voters they also need to win over: women, independents, and college-educated white voters.
