Ald. James Cappleman (46) will not run for a fourth term in the City Council next year after more than a decade at the helm of Uptown’s radical transformation, he announced in a note to constituents on Tuesday.

The news comes as three contenders have already lined up to succeed him — including one challenger who came within a hair’s breadth of unseating him in 2019.
