Maybe because they're catering to a vote bank that was most affected by manufacturing / factory jobs that went overseas? And there's little else those voters could relate to other than someone bringing back the jobs that they know well. There's also the righting the wrong thing that's appealing to many. As TFA points out there is little chance of revival of American manufacturing. TFA makes a very good point that most of those who lost their factory jobs have moved to service industry and that's what the candidates should focus on making better.
