It appears that Mr. Trump is having early success as the Carrier plant is on a path to keep its 1,000+ jobs at the Indianapolis factory.

On Thursday, Mr. Trump and Mike Pence, Indiana’s governor and the vice president-elect, plan to appear at Carrier’s Indianapolis factory to announce a deal with the company to keep roughly 1,000 jobs in the state, according to officials with the transition team as well as Carrier.

Mr. Trump will be hard-pressed to alter the economic forces that have hammered the Rust Belt for decades, but forcing Carrier and its parent company, United Technologies, to reverse course is a powerful tactical strike that will hearten his followers even before he takes office.“I’m ready for him to come,” said Robin Maynard, a 24-year veteran of Carrier who builds high-efficiency furnaces and earns almost $24 an hour. “Now I can put my daughter through college without having to look for another job.”It also signals that Mr. Trump is a different kind of Republican, willing to take on big business, at least in individual cases.
