Candidates usually campaign to let people know what they represent. They give speeches, meet with community leaders, and participate in debates . This process lasts for several months, and then the party members vote to decide who they want to back in the election. Usually rich people have more connections and can raise money more effectively. Most of our Presidents in the past have been relatively rich men, but not all of them.
Citizens go to a voting center and cast their ballot for the candidate of their choice.
Well, it's quite common for politicians to have themselves photographed kissing babies. It's their way of trying to appear in touch with the average American, but it looks really phony. These days, becoming President is all about acting. The candidates try to appeal to so many different people that they end up abandoning their own opinions. Sometimes, it feels like the parties are all the same.
