Joe Biden's campaign announced on Wednesday that it raised $26 million in the 24 hours after revealing Sen. Kamala Harris as his vice presidential pick.

Why it matters: The cash influx signals that Harris has helped the Democratic presidential campaign pick up steam. Nearly 150,000 contributors were first-time donors, according to the campaign statement.

The state of play: The Trump campaign said in a statement it surpassed the billion-dollar threshold with a cycle haul of $1.1 billion to date.

  • The Biden campaign, the Democratic National Committee and their joint fundraising committees, announced they raised $140 million in July, with $294 million on hand — a $50 million increase over the past month.
  • Yes, but: Biden out-raised Trump in May and June.

Democratic presidential nominee Joe Biden's campaign team released an ad on Twitter late Sunday in response to the New York Times' explosive report on President Trump's income tax contributions.

Why it matters: The ad and accompanying tweet stating how much tax American workers like nurses and teachers pay compared to the $750 in federal income taxes the NYT said Trump paid in 2016 and again in 2017 marks the first official response by the Biden campaign to the report, which Trump called "fake news." The ad comes ahead of the first presidential debate on Tuesday.

Progressives bide time for a Biden victory

Progressive Democrats want to beat President Trump so badly that they're tabling their apathy about Joe Biden — organizing hard to get him into office, only to fight him once elected.

Why it matters: That's a big difference from 2016, when progressives’ displeasure with Hillary Clinton depressed turnout and helped deliver the White House to Trump.
