BETHEL PARK, Pennsylvania — Just a few short months ago, if you drove down Baptist Road in this middle-class southern suburb of Pittsburgh, it would have been hard to miss the Bernie Sanders shrine filling the yard of a tidy, yellow-brick ranch home in the neighborhood. There was the life-size cutout of the former presidential candidate, a large "FEEL THE BERN" homemade sign along the berm of the road, a few "Bernie 2020" and "Get Berned" signs, as well as a lively decorated mailbox plastered with Bernie bumper stickers.
