As the 2016 presidential race moves closer to selecting party nominees for November’s general election, the list of presidential contenders that once included an ambitious 23 people has now dwindled to six.
Retired neurosurgeon Ben Carson on Friday became the latest candidate to drop out of the race, leaving just four people in a Republican primary that once included 17 candidates. Donald Trump, Florida Sen. Marco Rubio, Texas Sen. Ted Cruz and Ohio Gov. John Kasich remain.
On the Democratic side, former secretary of state Hillary Clinton and Vermont Sen. Bernie Sanders are the two candidates remaining after failed bids by Martin O’Malley, Lincoln Chafee, Lawrence Lessig and Jim Webb.
Take a look at the candidates who dropped out most recently and how much their campaigns spent, from Chafee’s $400,000 to Carson’s $53.7 million.
