Thursday could mark the beginning of the end for Bobby Jindal’s increasingly slim presidential hopes.

The Louisiana governor’s campaign reported having just $260,000 to spend at the end of September after raising a little over half a million dollars and spending significantly more than that in the third quarter. It’s a paltry sum compared to his rivals, and if Jindal can’t jumpstart his White House bid soon, he could be headed the way of Rick Perry and Scott Walker, who ended their campaigns when their coffers ran dry.

Jindal’s haul—or lack thereof—was the most ominous signal that came from the quarterly FEC filing deadline on Thursday, which showed that the top two Democrats, Hillary Clinton and Bernie Sanders, each raised more money between June and September than any of the 15 Republicans still in the race. (Donald Trump, of course, has access to more money than any of them through his own personal wealth.) Clinton raised $28 million and Sanders raised $26 million. Ben Carson’s rise to a close second in the polls was reflected in his fund-raising, as he led the GOP field by taking in $20 million in the third quarter.

The GOP donor and consultant class is poring over the reports for signs of how each candidate is managing their campaign. Advisers to Jeb Bush, for example, put out word to Politico that they’d be cutting back on spending, a day ahead of a filing that showed his “burn rate” was unsustainably high. Bush raised more than his Florida rival Marco Rubio, but because Rubio has run his campaign more frugally, he has more cash on hand—nearly $11 million to Bush’s $10.3 million. Bush’s fund-raising slowed over the summer as his poll numbers dipped. In cash reserves, Rubio trails just Carson and Ted Cruz, who leads all Republican contenders with a reported $13.5 million.
