“When you leave the two-thirds of Americans without college degrees out of your vision of the good life, they notice"
Clinton’s “trust problem” grew as the campaign progressed. Large numbers of voters didn’t trust her.
Looks like she was a victim of bad data analysis and a failure to perform surveys in the last 3 weeks of the election.
It looks like she stopped doing it when she thought she had the election in the bag and coast to victory.
the failure to notice the "lack of trust" by the voters is rather telling.
