Pence ended September with just $1.18 million left in his campaign account, a strikingly low number for a presidential contest and far less than his rivals, new filings show. His campaign also has $621,000 in debt — more than half the cash he had remaining — and is scrambling to meet donor thresholds for the Nov. 8 debate. While he would likely meet the debate’s polling requirements, Pence has struggled to gain traction and is polling in the low single digits nationally, with no sign of momentum.

Former President Donald Trump, meanwhile, is leading every one of his rivals by at least 40 points in national polls and ended September with $37.5 million on hand.

People close to Pence say he now faces a choice about how long to stay in the race and whether remaining a candidate might potentially diminish his long-term standing in the party, given Trump’s dominating lead. While Pence could stick it out until the Jan. 15 Iowa caucuses, visiting the state’s famous Pizza Ranch restaurants and campaigning on a shoestring budget, he must now weigh how that will impact his desire to remain a leading conservative voice, according to the people, some of whom spoke on condition of anonymity to share their unvarnished views.
