NYT:

New campaign-finance filings released this week revealed the degree to which Mr. Trump’s conviction on 34 felony counts on May 30 and Mr. Biden’s disastrous debate performance on June 27 became seminal moments in the fund-raising race….

The R.N.C., which had as little as $9 million in cash on hand at end of January, ended June with $102 million in its coffers, nearly double the $54 million it had at the end of May.

The committee’s cash increase is primarily a downstream effect of an enormous spike in small-dollar fund-raising after Mr. Trump’s conviction …. Mr. Trump and allied Republican groups raised roughly $69 million from May 30 — the day of his conviction — to May 31. The $34.5 million or so raised on each of those days more than doubled the record for the best online fund-raising day of the entire campaign by either party….

[Biden’s] best fund-raising days of the race so far came — perhaps surprisingly — after his unsteady debate performance at the end of June. Mr. Biden and his committees raised roughly $28 million over a two-day period between June 27, when the debate took place, and June 28.
