In warning for Trump, Democrat claims too-close-to-call Pennsylvania vote

The Democrat candidate claimed a congressional election in a Republican heartland in Pennsylvania, as a vote seen as a referendum on Donald Trump’s performance as president remained officially too close to call early on Wednesday.

In an ominous sign for Republicans eight months before national midterm elections, official results with all ballots from voting booths counted showed moderate Democrat Conor Lamb leading conservative Republican Rick Saccone by a fraction of a percentage point.

Trump won the Pennsylvania 18th Congressional District that they are contesting by almost 20 points in the 2016 presidential election.

With TV networks, which often call U.S. elections, yet to predict a winner, officials were continuing to count several hundred absentee ballots to try to determine the result.

Democratic sources said that, once those ballots were included, they expected Lamb to have won the election by more than 400 votes.

“It took a little longer than we thought but we did it. You did it,” Lamb, a U.S. Marines veteran, told cheering supporters late on Tuesday.

Speaking before Lamb claimed victory, Saccone - who has described himself as “Trump before Trump was Trump” - said the contest was not yet over.
