The United Auto Workers strike could be the canary in the coal mine for Biden's reelection pitch to working-class voters

• The UAW union late last week went on strike to pressure the "Big Three" to raise worker wages.
• The strength of President Biden's economic message could hinge on the outcome of the strike.
• Biden has sought to sharpen his 2024 economic pitch, but voters aren't fully sold on his message.

Shortly after Joe Biden launched his 2020 presidential campaign, his first major rally was held at a Teamsters union hall in Pittsburgh, where he extolled the virtues of middle-class Americans.

Referring to himself as a "union man," Biden mapped out of his vision of an economy that would empower ordinary citizens by lifting wages and targeting financial loopholes that favored big businesses.
