In a dramatic showdown in the Senate, Sens. Joe Manchin of West Virginia and Kyrsten Sinema of Arizona delivered a decisive blow to their former party colleagues by voting against a key nomination.

Their "no" votes opposed the renomination of Lauren McFarren to the National Labor Relations Board (NLRB), highlighting their independence from Democratic Party lines and the wishes of Majority Leader Chuck Schumer, as Axios reports.

The outcome was a significant setback for Schumer, who had pushed hard for McFarren's renomination. The vote took place amidst a closely divided Senate where every decision holds substantial weight due to tight margins.

Sinema's Return and Manchin's Timeliness

Sinema made headlines as she cast her opposition vote during her first return to the Senate since the Thanksgiving break. Her decision foreshadowed the ultimate result, which was only confirmed when Manchin arrived just in time to cast his own vote.

Manchin, who had been attending another event, shifted the anticipated 49-49 tie to a definitive 50-49 outcome. In doing so, he made the participation of Vice President Kamala Harris, who often serves as a tie-breaker in the Senate, unnecessary on this occasion.

Pressure on Senate Democrats

For Schumer and other Democrats, keeping control of the NLRB under the upcoming Trump administration was pivotal. Pressure had been mounting from both progressive senators and labor allies to secure McFarren's appointment, someone noted for her track record in supporting worker rights.

Nevertheless, uncertainty lingered until the last moment regarding how Manchin and Sinema, now independents, would vote.

Throughout their term, both have shown a penchant for voting contrary to Democratic Party desires, as seen in their opposition to President Biden’s legislative priorities and nominations.

A History of Independent Decisions

Manchin and Sinema's decision to leave the Democratic Party over recent years underscores a broader pattern of defying party expectations. Sinema parted ways with the party in late 2022, while Manchin followed suit in March 2024.

Their resistance to party pressures has been consistent, notably in significant legislative battles such as the Build Back Better agenda and crucial nominations including that for the labor secretary and the Office of the Comptroller of the Currency.

Schumer's Disappointment and Broader Implications

Reacting to the vote's outcome, Schumer expressed his deep disappointment. He viewed it as a direct affront to labor advocates and expressed concerns about the implications for workers' rights moving forward.

He stated that McFarren was a "highly qualified nominee" who had a proven track record of advocating for workers, making the result all the more troubling for those relying on a Democratic-controlled NLRB to support labor interests in the face of potential policy shifts under Trump.

Republican Presence Was Near Perfect

Senate Republicans contributed to this defeat by maintaining near-perfect attendance. The GOP's cohesion was underscored by the absence of only one member, Sen. Roger Marshall of Kansas, who missed the vote due to a scheduled orthopedic surgery.

By capitalizing on disciplinary attendance and the support of the two independents, Republicans managed to block McFarren's return to the NLRB.

Manchin and Sinema Play Spoiler

In the wake of the decision, Manchin clarified his stance, emphasizing that his opposition was not a personal matter but rather centered on specific policy differences, such as McFarren's approach to joint employer regulations.

Neither Manchin nor Sinema's votes came as particular surprises to those familiar with their legislative tendencies, despite causing dismay among colleagues who had hoped for their support.

As the political arena braces for more shifts under the incoming administration, the vote serves as a vivid reminder of the complex dynamics at play in the Senate.

It highlights the ongoing impacts of individual autonomy within the legislative process and the potential for unexpected outcomes in the nation's governance.
