Vice President Kamala Harris was already facing some political headwinds in the form of negative polling following a brief “honeymoon” period over the summer after President Joe Biden decided to end his reelection bid and anoint her his successor, but now a new issue could spell doom for her campaign.

Thousands of dock workers walked off the job on Tuesday morning in protest of the government’s refusal to intervene in longshoremen’s negotiations with shipping corporations, delivering a significant blow to the current administration and an already struggling economy.

The historic strike has halted operations at many ports along the eastern seaboard, threatening the fragile but recovering economy and raising questions about Harris’s electoral prospects.

Prices for goods ranging from construction materials to Halloween decorations and Christmas gifts are expected to rise, adding to Americans’ economic concerns just weeks before they decide if the Democrats can effectively reduce consumer prices. Recent polls have shown that voters are giving Trump an advantage when asked who they trust most to grow the economy.

Politicians scrambled to address the walkout. New York Governor Kathy Hochul, who oversees some of the top 10 busiest eastern ports, said in a statement to ABC News, “Moments ago, the first large-scale eastern dockworker strike in 47 years began at ports from Maine to Texas, including at the Port Authority of New York and New Jersey. In preparation for this moment, New York has been working around the clock to ensure that our grocery stores and medical facilities have the essential products they need.”

Union leaders, however, have already been pushing back.

“We are prepared to fight as long as necessary, to stay out on strike for whatever period of time it takes, to get the wages and protections against automation our ILA members deserve,” ILA President Harold Daggett said in a countervailing statement. “Right now, everything is off the table,” Daggett told FOX Business. “Nobody’s talking right now. We got Congress trying to bring them to the table. And that’s where we are right now.”

Experts warned that prolonged disruptions could quickly cause positive economic news from recent rate cuts to dissipate. “A strike would be very, very disruptive,” said Jason Miller, a professor of supply-chain management at Michigan State University who closely tracks imports, told ABC News.

“You can’t take all this freight and either send it to other ports or put it on airplanes,” Miller added. “There is no plan B.”
