From the Daily Beast here:
In the final months of the brutal and chaotic 2016 campaign, there were plenty of Democratic activists freaking out about Wisconsin, Michigan, and Pennsylvania (the three states that ultimately cost the Democrats the White House) and Clinton’s fatal shortcomings there. Many of them were envoys of the Sanders camp who wanted to help fix those problems, including Clinton’s difficulties with the block of the mythical “white-working-class,” economically anxious voters who Sanders had championed during the primaries.
Out of touch!
Out of luck!
And this sure as shit is not Russia’s fault, this is the fault of Hillary Clinton and her campaign.
