From the AP results (Google "Presidential Election Results" and use the pull down menus to get the election results for the House of Representatives from Pennsylvania):
Conor Lamb: 219,858
Sean Parnell: 211,272
Fifteen days after the election and Representative Lamb is still ahead by about 8600 votes. This late in the process, Sean, where are you going to find 8600 votes?
Sean, it's time for you to concede.
