The pro-Jeb Bush super PAC Right to Rise on Friday ordered a series of shifts in TV advertisement time – a decision that is potentially fraught with implications for Bush’s candidacy.

The group had planned to begin airing commercials on Monday in Virginia, Tennessee, Texas, Georgia, and Oklahoma – all states that hold primaries on March 1. But Right to Rise on Friday moved the start dates for the ads three days later, to Thursday, according to two media tracking sources.

The shift appears small. But in altering the start date from Monday to Thursday, Right to Rise gives itself the opportunity to save money in the event Bush decides to end his campaign following the New Hampshire primary. Most polls in the state show the former Florida governor trailing far behind front-runners Donald Trump and Marco Rubio. Bush has made New Hampshire the cornerstone of his campaign.
