Democrat Kamala Harris faced Republican Donald Trump on Tuesday in the U.S. presidential election, after the two candidates vied for support by staking positions on issues including abortion, the economy and foreign policy.

Polls in most of Pennsylvania, one of the most closely watched swing states, as well as 16 other states, are now closed. Preliminary results of the Pennsylvania exit poll appear in favor of Harris, according to CBC News. With about 7.6% of the expected votes counted, Kamala has secured a 73.1% majority. The state holds 19 electoral votes.

Exit polls help us better understand who came out to vote, how different groups of people voted and how they feel about some of the biggest issues of the campaign.
