Electing our leaders is at the core of American democracy. That includes electing a mayor, a governor, a senator, a representative, or the president.
Getting elected to any office is a hard process. That’s even more true of getting elected to the presidency. Any election involves political parties, primaries, conventions, campaigning, money, and voting.
Most people who run for president have already served in government. They may have been the governor of a state, or a senator or representative. It’s not required, but it is common. Having already served in government is great job experience.
Most individuals who run are also relatively well known. Having name recognition at the start of a campaign makes it easier to get support and votes.
