Trump has less money at this point in the election than any other recent major-party presidential candidate.

The Trump campaign has not raised a significant amount of money from donors, relying instead on loans from Mr. Trump. The campaign ended May with less than $1.3 million on hand. The Clinton campaign, in comparison, has been raising money at a rate more on par with presidential candidates in recent elections.

Clinton’s staff is almost 10 times as large as Trump’s.

Mrs. Clinton’s campaign had many more people on its payroll in May. Mr. Trump has had a small staff throughout the primary months and has yet to hire people for field offices in swing states. He has said he will rely on the Republican National Committee to fill many of these roles.

But Trump won the primaries while spending only a small fraction of what the other leading candidates spent.

Mrs. Clinton and Senator Bernie Sanders of Vermont have spent more than twice as much money as Mr. Trump.

Despite spending little on advertising, Mr. Trump had a news media presence that dwarfed those of other candidates, with pervasive coverage of his campaign on television, in print and on social media. According to mediaQuant, Mr. Trump earned $639 million in free media in May — more than double Mrs. Clinton’s $275 million.
