Washington — Louisiana Gov. Bobby Jindal’s campaign for president took in just under $580,000 in contributions from July 1 to Sept. 30, an amount that lags far behind his leading rivals for the 2016 Republican presidential nomination, according to federal fundraising reports filed Thursday.

The amount is less than $1,000 more than the Jindal campaign raised in the April-June quarter, even though his campaign committee did not began to accept reportable contributions until mid-May.

The total reported Thursday includes only money contributed to Jindal’s official campaign committee. His White House bid is also supported by three independent groups, which detail their activities on a different schedule. As of June 30, those groups had taken in a total of $8.6 million, according to federal filings and information from the Jindal camp.

Donations to the campaign committee are held to strict limits: A maximum of $2,700 per individual and of $5,000 per political action committee, with nothing at all allowed from corporations or labor unions. Donations to the independent groups are unlimited by size or by source within the United States. Because of the limitations for campaign committees, their success in raising money is seen as a telling indicator of the breadth of support for candidates.

The candidate can directly control spending by the campaign committee, which also qualifies for TV advertising discounts. Spending by independent groups cannot be coordinated with the official campaign, legally, but the boundary is fuzzy and enforcement is lax. One of the outside pro-Jindal groups — Believe Again, a single-candidate super PAC — has sponsored dozens of town-hall meetings with voters in Iowa and spent $2.5 million on TV advertising in that state, which hosts the Feb. 1 caucuses that launch the formal nominating process.

A recent poll in Iowa showed Jindal at 6 percent — his best showing in months — which tied him for fifth with two other candidates. But he has fared far worse in national polls, routinely scoring at or below 1 percent.

The third-quarter official campaign fundraising reports are due by midnight Thursday night.

The top July-September fundraiser in the Republican field, based on reports filed by late afternoon Thursday, is retired neurosurgeon Ben Carson, with $20 million. Other totals include: former Florida Gov. Jeb Bush, $13.4 million; U.S. Sen. Ted Cruz, of Texas, $12.2 million; former Hewlett-Packard CEO Carly Fiorina, $6.8 million; U.S. Sen. Marco Rubio, of Florida, $6 million; and U.S. Sen. Rand Paul, of Kentucky, $2.5 million.

In addition, the campaign of New Jersey Gov. Chris Christie said it had raised $4.2 million in the period. And the campaign of Wisconsin Gov. Scott Walker filed a federal report showing contributions of $7.4 million, even though he quit the race in late September in the face of plunging poll ratings and dwindling cash reserves.

The Jindal campaign reported spending $832,000 in the third quarter, leaving it with $261,000 in cash on hand on Sept. 30.

Of the slightly more than 300 individual contributions reported, 57 percent were listed for donors with Louisiana addresses.

The campaign reported a single $5,000 PAC contribution, from the Crescent River Port Pilots’ Association.
