I'm not trying to be a jerk. I'm having a tough time understanding your point. The Constitution spells out the role of the President and the function of the Executive Branch (he runs that) as well as the Judicial and Legislative Branches. If you've read that document (or, alternatively, listened to Schoolhouse Rock) then you know what the POTUS does. I'm sure you understand that the President largely sets the agenda for the country, and if he is successful in convincing Congress to see things his way, that they will pass the legislation he/she wants. Or, he/she can appeal directly to the public, which can put pressure on Congress, and result in legislation. And, the POTUS makes judicial appointments, which affect our lives in countless ways. And, the President promulgates executive orders which can affect which laws get enforced and how, and can influence policies below the level impacted by laws. And he/she can appoint either effective or ineffective people to run huge government agencies and to represent the US as Ambassadors overseas. Some people think that is important. And, the President sometimes travels directly to foreign countries and meets with their leaders, sometimes these meetings result in important agreements. And, the President is the only person empowered to sign treaties on behalf of the United States--these treaties are agreements between the US and other nations/international bodies. Some people think this is important. That and more--it's in the 'ol Constitution.
Anyway, it's nothing personal. I'd urge anyone who doesn't believe the job of President is important or doesn't know what it entails to stay home on election day. It's really a civic duty.
