“We are declaring a victory in Pennsylvania. This is not based on gut or feel. This is based on math,” Trump campaign manager Bill Stepien said on Wednesday in a conference call with reporters.Currently, President Trump holds a margin of about 454,000 votes in Pennsylvania and 1.12 million votes are still outstanding. For Biden to win, the campaign estimated, he would need to win 78 percent of the remaining votes.Stepien noted that there were still 170,000 votes in Philadelphia County, and 61,000 in Montgomery County, both of which favored Biden. But there were still a lot of votes coming from “Trump Country” areas of Pennsylvania such as York County, Butler County, and Blair County.
