Which candidates have been focusing on jobs, especially in the rust belt

that pay well and that can confer a sense of pride. People in the rust belt see those slipping away. Not easily solved, and certainly haven't been hearing too much focus on these yet. What ideas are out there? Retraining, sure that's a good idea-- but people want to know that there will be an employer for the new job they have been trained for. This may be key issue that determines who wins the general election.
