Elected officials have to campaign for reelection every time their term is up, but, for the most part, the first time is the real challenge; incumbency is a strong advantage in elections. More than 90 percent of the U.S. House of Representatives is reelected every two years, and the reelection rates at the lower levels of politics are similar. There is no one career path which reliably leads to an elective office. Working as an aide for an established politician is one common way to meet contacts in the local political party apparatus. Law school is another common first step to a political career, since many lawyers achieve public notice and visibility or do work for state political parties.
