Donald Trump spent more on hats than Louisiana Gov. Bobby Jindal raised in three months. Democrat Martin O’Malley’s fundraising for the quarter was dwarfed by rival Bernie Sanders’s haul in just the 24 hours after Tuesday’s debate. And Hillary Clinton’s parking expenses surpassed Lincoln Chafee’s entire third-quarter haul.

Campaign finance disclosures filed Thursday gave a comprehensive look at the candidates who sit atop the presidential field—and those who seem ready to leave it.

On the very bottom rungs of the third-quarter money race are Mr. Chafee, a Democrat and former Rhode Island governor who raised $15,000 and owes himself more than $360,000, and Republican Jim Gilmore, the former Virginia governor who raised $105,000. His campaign has $34,000 in the bank — and is $43,000 in debt.
