The applications began streaming into Gov. Brian Kemp’s office almost as soon as the Republican encouraged anyone interested in succeeding U.S. Sen. Johnny Isakson to apply online.

More than 500 people had filled out a short questionnaire and submitted their resumes to seek the coveted spot, which is opening after Isakson announced he's stepping down at year's end for health reasons.

Whoever Kemp picks would stand for election in November 2020 to fill out the remaining two years of Isakson’s term – and be expected to run again in 2022.

Among the biggest names seeking the appointment are business executive Kelly Loeffler, U.S. Rep. Doug Collins, and House Speaker Pro Tem Jan Jones, the No. 2 Republican in the state House.

Some other well-known figures are aiming for the seat, too, including current and former state lawmakersa U.S. ambassadordecorated military veterans, radio commentators and former Kemp aides.

The public nature of the process has led some potential contenders, including U.S. Attorney BJay Pak, to opt out. Others, including business executives, statewide politicians and judicial leaders, stayed on the sidelines.

"This application process is the wildest contest since the search for golden tickets in Willy Wonka and the Chocolate Factory,” said Josh McKoon, a GOP activist and former state senator.
