UAW STRIKE EXPOSES TENSIONS BETWEEN BIDEN'S GOALS OF TACKLING CLIMATE CHANGE AND SUPPORTING UNIONS

The strike involves 13,000 workers so far, less than one-tenth of the union's total membership, but it's a sharp test of Biden's ability to hold together an expansive and discordant political coalition while running for reelection.

Biden is trying to turbocharge the market for electric vehicles to reduce greenhouse gas emissions and prevent China from solidifying its grip on a growing industry. His signature legislation, known as the Inflation Reduction Act, includes billions of dollars in incentives to get more clean cars on the roads.
