The results out of South Bend tell it all: Barack Obama‘s success in urban counties and with young voters cut into Hillary Clinton‘s success in blue collar, working-class areas.
St. Joseph’s County, which is where South Bend and North Dame are located, was such an interesting county to watch because it has strong traditions of both ethic, working-class Catholics, who have been favoring Clinton, and young, more liberal college students, who have been choosing Obama. Obama ended up winning this crucial battleground with 53%, which explains in part why he was able to hold Clinton to only 51% statewide.
Elsewhere in Indian, Clinton showed dominance in the southern parts on the state, racking up huge margins along the Ohio River Valley, just like she had done in the Buckeye State. Obama ran very strong in Indianapolis and Lake County, which borders on Chicago.
