ALTOONA, Pa. — President Trump’s road to re-election runs through places like Altoona, with its deep working-class roots, conservative social values and nearly all-white population. But it is not a straight line.

He won about 70 percent of the vote in Blair County, where Altoona is the largest city, in 2016, and that support was an integral part of why Mr. Trump defied forecasts and carried Pennsylvania, a state that will again be critical to his chances in 2020, by about 44,000 votes.

Altoona’s voters have now had more than two years to assess whether Mr. Trump has honored his campaign commitments and whether they will support him again so enthusiastically. Their answer, judging from interviews with more than two dozen voters, is complicated, not the black and white narrative that either Mr. Trump’s supporters or his critics might assume.
Most of his supporters say they will stick with him, citing his blunt style, which some of them see as a form of entertainment, as well as a strong economy. But not all of them.
