Bradley Bowman who advised republican senators on foreign policy says what he expects a Biden presidency would mean,

请教老师： 对于这句says what he expects a Biden presidency would mean t他期望拜登当选总统意味着什么
expect的宾语是what,那样后面的a Biden presidency是什么问题呢？
了解谓语是would mean, 但对于主语what he expects a Biden presidency没搞清what he expects 和 a Biden presidency之间的关系？
Bradley Bowman says what （he expects） a Biden presidency would mean, you would see continued emphasis on encouraging our European...
划线部分为says的宾语从句。该宾语从句为嵌入式名词性关系分句。即宾语从句本身又是一个带有宾语从句的主从复合句，其中he expects为主句，what a Biden presidency would mean这个名词性关系分句为宾语从句。what是名词性关系分句的宾语。
you would see continued emphasis on encouraging our European...这个分句为补充语，对what作补充说明，其前的逗号等于破折号或冒号。
