I think Hillary won by like ~60 votes. (college town)
If you're talking about the borough of Millersville, she won by about 250 votes. The totals were
Clinton: 1627
Trump: 1374
Castle: 14
Stein: 41
Johnson: 151
Don't believe everything you read in LNP! I happened to pick up a copy of that rag this morning and I saw that it reported that "Trump won Lancaster City." (?!) That's the most reliably Democrat part of the county, even more than Millersville. I was astonished at that claim so I looked it up on the county website to be sure. Here are the totals for the city of Lancaster:
Clinton: 21193
Trump: 7255
Castle: 143
Stein: 390
Johnson: 958
