Not so long ago, the best way to become president was to join the army and serve your country with distinction. A bit later, it was to work your way up the ranks of elected official, governor, Senator, and then into the White House. These days, the best route seems to be becoming famous and then using your celebrity to get loads of people to vote for you. Gone are the days of your Dwight D. Einsenhowers, your FDRs, your JFKs. Gone, even, are the days of Ronald Reagan, who started as an actor, before switching late to the whole governor-White House trail. Today, it’s reality shows and showmanship that win you elections, and they may be here to stay.
