(AP) — Democratic Party left wing leaders Bernie Sanders and Elizabeth Warren are at risk of being excluded from the senior ranks of President-elect Joe Biden’s administration as Biden balances the demands of his party’s progressive base against the political realities of a narrowly divided Senate. The liberal New England senators remain interested in serving in Biden’s Cabinet, but even some of their allies recognize they face major political hurdles getting there. Sensing disappointment, progressive leaders have reluctantly begun to express support for less-controversial alternatives. The scrutiny on Biden’s staffing decisions reflects the tremendous pressure the president-elect faces as he cobbles together a team to execute his policy priorities.
