Clinton's success with European-American Catholic voters

Ever since the days of the "Reagan Democrats", European-American Catholics increasingly vote Republican. However the Clinton campaign sees an opening, and polls show she's winning this important demographic. The shift towards Clinton owes partly to the recent sexual harassment scandals involving Trump that offend many of the devout. At the same time Pope Francis' has moved the church to emphasize service to the poor versus issues of morality like abortion and gay rights.

Bosnian Americans play a pivotal role in presidential election

During a previous religious based world conflict, it was Bosnian Muslim refugees who arrived in the US seeking refuge. Many settled in Saint Louis, Missouri. That state is considered a swing state in national politics, with recent polls show Missouri in a dead heat between support for Trump and Clinton. Bosnian and Kosovar immigrants in the St. Louis are could play a role in pushing Missouri over the top for Clinton. Although of European origin, these groups are still mostly Muslim, and are disheartened by Trump's anti immigrant and anti-Muslim rhetoric.
