Four top Presidential candidates are dangerously close to emptying out their bank accounts for their campaigns.
Those four are Joe Biden, Pete Buttigieg, Amy Klobuchar, and Elizabeth Warren. They face the increasing threat of a well-funded Bernie Sanders whose recent rise in the race for the Democratic nomination has only made his fundraising stronger. They also face a well-funded Mike Bloomberg since he has self-funded his campaign with his own fortune.
Elizabeth Warren is the closest to being in the red with only 2.3 million in her account (Politico).
