How Joe Biden Is Catching Up to the Trump Money ‘Juggernaut’

Mr. Trump’s campaign and the R.N.C. are paying top staff members significantly higher salaries than the Biden campaign and the Democrats. More than 20 of Mr. Trump’s campaign aides and R.N.C. officials are paid a higher salary that Mr. Biden’s campaign manager, for instance. Mr. Parscale is paid more opaquely, with monthly payments of $47,797 going to Parscale Strategy L.L.C., quadruple what Ms. O’Malley Dillon has received.

The highest paid officials were the party leaders, and there was a gap there, too: Ronna McDaniel, the R.N.C. chairwoman, was paid more than $24,000 in May; Mr. Perez was paid less than $16,000. (“A woman in the same position is making more because she is beating her male counterpart in nearly every metric,” said Michael Ahrens, an R.N.C. spokesman.)

In May, Mr. Trump spent $470,925 on polling, including $98,000 to the firm of John McLaughlin. Mr. McLaughlin wrote a memo this month titled “Skewed Media Polls,” which criticized surveys that show Mr. Trump losing the election, and the memo was recently posted on Twitter by the president. In contrast, Mr. Biden’s campaign spent only $122,300 on polling. (The R.N.C. spent another $2.5 million that was listed as “polling services/consulting” last month, which a party official said encompassed its voter data operation; the D.N.C. listed zero polling expenses.)

The Trump campaign and Republican Party also spent far more on legal fees — $1.55 million to $875,000 — than Mr. Biden and the Democrats in May.

One of the biggest shifts in the cash race is that Mr. Biden’s campaign is now regularly holding multimillion dollar fund-raisers, partly because the contribution limits for the presumptive nominee and the party are more than 200 times as high as during the primary. In June, Mr. Biden has raised a combined $21.6 million from just six of the virtual fund-raisers for large donors he has held.

And while Mr. Biden, during the primary race, had to compete with the next generation of Democratic talent, he is now able to leverage their networks, particularly those under consideration to be his running mate.

Senator Elizabeth Warren of Massachusetts held an event with Mr. Biden this month that raised $6 million in an evening, the campaign’s largest single fund-raiser. Unlike the Obama event, Ms. Warren’s relied on some major contributors. A few days earlier, Senator Kamala Harris of California organized an event that pulled in $3.5 million; Gov. Michelle Lujan Grisham of New Mexico helped host another event that an organizer said raised $1.7 million; and Susan Rice, the former United Nations ambassador, headlined a fund-raiser last week that Mr. Biden did not attend.
