Of course you can. Trump ended up winning fewer votes than Romney and McCain. The shame directed towards those that supported him publicly, I would argue, was very directly reflected in his vote totals.

But you need more than that, you need an inspiring alternative. Telling a bunch of destitute, hopeless rust belt voters that free trade was good, their Obamacare premiums were increasing, a $15 minimum wage and free college tuition was bad, and America was already great didn't motivate them to go to the polls nearly enough. Should be unsurprising, in retrospect.
