Green Party Leadership Shift with Polanski's Victory
Polanski studied drama in Atlanta, Georgia, and joined Liberal Democrats in 2016.
He switched to Green Party in 2017 and elected to London Assembly in 2021.
Polanski, 42, is praised for energizing grassroots and a #BackZack video with 1.5M views.
He apologized after a 2013 Sun article prompted controversy.
Polanski aims to attract progressive voters disillusioned with Labour's leadership.
His victory may shift Green Party strategy amid tensions over polarizing rhetoric.
