Will we be better off Blue or Red What is the Role of the President

There is a lot of talk today about the two US Senators who are running for the highest office in the country, if not the world. Both candidates will probably spend over 1/2 billion dollars for a four year commitment salary of $400,000.00 and probably age 12 years in 4 years. Who ever wins, will not have a normal life. Every time they go somewhere they will be followed by secret service, staff, reporters, curious citizens, weirdos. They will be fighting everyday with man and woman in the government that have little or no common sense. Whoever is elected will inherit someone's work and have to fix their mistakes and create new ones. Why would someone who has a family want to do something like this?
