US House Election Vote in Pennsylvania Too Close to Call by VOA News Polls have closed in a tight special election race in Pennsylvania, where Republicans are hoping to prevent the 18th Congressional District from falling into Democratic hands. With vote counting underway with the race was too close to call late in the evening. Nearly three hours after polls closed and with 99 percent of precincts reporting, unofficial results had Lamb leading Saccone by fewer than 100 votes. The fight between Republican State Representative Rick Saccone and Democrat Conor Lamb has drawn national attention as a bellwether for the midterm election in November. President Donald Trump won this Pittsburgh-area district by about 20 points in 2016, but it's Lamb who has run a high-energy race to challenge Saccone, after Republican Representative Tim Murphy resigned last year amid a sex scandal. A Monmouth University poll released Monday showed Lamb, a 33-year-old Marine veteran and former prosecutor, with a slight lead over the 60-year-old Saccone among likely voters. If Lamb wins, it would signal precarious times for Republicans even in solidly red areas, and underscore just how little help Trump might provide the party this fall. For the White House and its Republican allies, a Tuesday loss would represent both an embarrassment and a major cause for concern in the broader push to defend its House and Senate majorities.
