How the Democrats lost their grip on the blue collar vote
...The current group of Democrat candidates further alienates union voters by pushing the Medicare for all which would mean they would lose the healthcare insurance they have bargained for over the years which is superior to Medicare. While they might not like Trump's style his policies have directly benefited unions by bringing millions of jobs back to this country and by attacking China's theft of jobs and intellectual property which creates those jobs.
It was the promise of “card check” legislation, which would have made it easier for workers to unionize, which first energized the labor movement for Obama in 2008, fueling donations and grass-roots support.
But even with Obama in the White House and Democrats holding healthy majorities in both the House and the Senate, working-class voters were rewarded with no labor-law reform in 2009 or 2010.
As a result, non-college whites fled the Democrats during the 2010 midterms, when they supported GOP candidates by double digits, turning the House of Representatives red.
This cohort leans Republican now more than ever; a Gallup poll this year shows they favor the GOP by a whopping 25 percentage points.
It was as if the Democratic Party didn’t understand how much they needed labor. Oddly, it appears they still don’t. “The working-class voters in my county tend to wonder if the party still wants them,” says Mark Hackel, the Democratic chief executive of Macomb County, Mich., where voters favored Trump over Clinton by 11 percentage points. “They’re not really sure where they fit in.”
Mike Mikus, a Democratic strategist who helped guide Pennsylvania Gov. Tom Wolf’s successful reelection last year, said it would be folly if his party didn’t start wooing the working-class voter.
