As the head of state, the president acts as the highest living symbol of our country. When he welcomes Super Bowl champions to the White House or hosts an official dinner there, he is representing the nation. The president also engages with foreign leaders. His actions are expected to represent the nation’s top ideals and commitment to democracy. The president serves as the leader of his political party and plays a key role in shaping its positions on important issues. He helps raise money for the party and campaigns for members who have supported his policies and are running for office. Experts say that Barack Obama (2009-2017) reshaped the Democratic Party during his presidency.
