The politics of the port strike

The ramifications of the US dockworkers strike that began Tuesday could inject uncertainty into the 2024 presidential campaign, create a new sense of unease around the US economy, and be directly felt in key swing states from Georgia to Michigan.

Much of the unease hinges on how much — and how long — any effects will be felt now that port workers on the East and Gulf coasts have walked out.

"If it lasts for more than a few days or more than a week, you're going to get massive cascading effects," Flexport founder and CEO Ryan Petersen said in a recent Yahoo Finance appearance, noting that 15% of the world's container ships could be caught up in a stoppage.

"That's a huge reduction in capacity," he added.

But a prolonged shutdown in Georgia, North Carolina, and in other major ports in the East and Gulf coasts could increase Americans’ sense of economic unease after negotiations stalled over a complex series of wages and automation issues.

There are also significant question marks about how Kamala Harris and Donald Trump will approach the strike — with much of the campaign trail focus in recent days on other topics such as the aftermath of Hurricane Helene. The back-and-forth plays into complex politics around unions in the 2024 race amid a concerted effort by Donald Trump to gain labor support.

Economic problems could also quickly spread to other parts of the country that will also have a say in the November election, like Michigan, if shipments of autos and auto parts are held up.

But shipping experts said that President Joe Biden could be drawn directly into the standoff and be forced to step in to keep workers temporarily on the job.

"We strongly suspect that, this close to the election and despite denials ahead of time, President Biden would have little choice but to step in and invoke back-to-work legislation," Bradley Saunders of Capital Economics wrote in a recent note.

Such a move could trigger an 80-day "cooling off period" and largely — but not completely — shelve the issue until after Election Day.

The White House said such a move isn't on the table, but it is increasingly being drawn into the standoff.

Last Friday, Transportation Secretary Pete Buttigieg, Acting Labor Secretary Julie Su, and Director of the National Economic Council Lael Brainard met with the port operator, the United States Maritime Alliance, to convey a message "that they need to be at the table and negotiating in good faith fairly and quickly."
