Before getting this job, no one will give a shit about who you are. When you get this job, everyone in the country (whether conservative or liberal, Democrat or Republican, etc.) will hate you at one point or another. After you leave this job, people will either praise you to high heaven or bitch about how badly the country is doing because you were the President.
political figurehead that all of America blames their problems on, acting as if the president had any real power and was diliberately making horrible decisions.
