ever since wwii tmthey always did hated each other.

jacksonian era promoted strength of the presidency and executive branch at the expense of congress. it also sought to broaden the public's participation in government. the jacksonian's demanded to have elected judges, instead of appointed judges, and rewrote many state constitutions to reflect the new values. hope this ! if you did find it would you mind giving me brainliest? : )
