I don't think that's true. I think many Rust Belt and midwest voters know full well the kind of industry booms their parents and grandparents enjoyed aren't happening again, and that their coal and manufacturing jobs are going to continue to decline no matter what Trump does. Maybe there's some set of polling data that disproves this, but I believe many -- not all, maybe not even most, but many -- of these people voted for Trump not because they believed the lie but they appreciated the shout out that, rightly or wrongly, they believed they weren't getting from Hillary Clinton: an imperfect messenger on an average day, but particularly in this campaign when her defining statement on coal country was that her administration would put these people out of business! You can't come back from that with these people.
Hillary had a jobs retraining plan, she had a plan for creating thousands of new jobs in the green energy sector, she had a plan for more accessible higher education -- and when the voters who would principally benefit from those plans swung for Trump instead, it's easy to conclude, that they don't want the truth, they want the lie. Which is probably true for a lot of these voters. But I think there are just as many voters who just don't want to be told the solution to their pain is to read Hillary Clinton's website after hearing her say "We're going to put a lot of coal miners out of business."
