President Joe Biden is heading into the general election in must-win Michigan without the backing of the top Democrat in one of its most pivotal counties and with fractures among his Democratic base.

Macomb County Executive Mark Hackel said he’s not endorsing Biden in 2024 and has no plans to campaign for his party’s Democratic nominee. 

Hackel’s decision to sit on the sidelines could be detrimental to Biden’s chances in the Detroit suburb as the longtime Macomb leader is the most popular politician in the county with crossover appeal to both Democrats and Republicans.

While he’s not endorsing former President Donald Trump either, Hackel raised concerns over Biden’s effort to win Macomb and questioned why no one from the president’s campaign has contacted him for support.
