The outcome Tuesday of 2018's first congressional elections is a barometer ahead of November's midterm elections. "The scary thing for vulnerable House Republicans this year is that neither the National Republican Congressional Committee nor [aligned super PAC] seem to have any clue what to do about it", Tyler Law, spokesperson for the Democratic Congressional Campaign Committee told ABC News in an email.
Murphy, an eight-term congressman who had union support, never had a close election and had no Democratic challenger in his last two elections.
But Trump acknowledged that Saccone was in a "tough race" and urged his supporters to come out and vote.
Mr Trump vowed to fight any retaliatory trade measures by, for example, slapping taxes on imported European cars.
Trump stumped alongside Saccone on Saturday, blasting "Lamb the sham" and pushing for support of Saccone because "the world is watching".
"He believes in hard work, he believes in labor", Biden said, referring to Lamb's working-class credentials. More than 80,000 people in the district are in union households, with almost 18,000 of them affiliated with the steelworkers' union.
During the rally, Trump said the South Koreans support his efforts and even credited him with making last month's Winter Olympics a success. "When you catch a drug dealer, you've got to put him away for a long time".
"The only way to solve the drug problem is through toughness". But these people are killing our kids and they're killing our families, and we have to do something. "I don't think we should play games". "I don't know if we're ready - I don't know if this country's ready for it", he said.More news: Congress' list of candidates for Rajya Sabha elections

Trump faulted his predecessors in the Oval Office beginning with President Obama and going back to Presidents George W. Bush and Bill Clinton for failing to rid North Korea of its nuclear capabilities. But by the next day, the coverage had turned.
"You saw yesterday's numbers - yesterday's job reports were among the best number produced in the history of our country", he said.
President Donald Trump said he was open to the idea of executing drug dealers Saturday in a speech, and attributed the idea to Chinese President Xi Jinping, The Hill reported. You've got to know, he's an extraordinary person. "A little hard to sell tickets when you think you're going to be nuked", Trump joked. He had discussed his message on North Korea with aides shortly before taking the stage. And there was a nice unity.
The president said he's decided on a slogan for his 2020 re-election campaign.
"The task for everyone here tonight is to make sure that this great American comeback continues".
The White House also recognizes the threat of losing a seat Rep. Tim Murphy (R-PA) won easily for years until an embarrassing sex scandal forced him from office. He added that a Winfrey candidacy would be a "painful experience for her".
"Oh I'd love Oprah to win, I'd love to beat Oprah".
"There's also a segment of undecideds that hopefully they'll remember why they voted for Trump to begin with, and they'll come out and vote for me", Saccone said before talking to natural gas workers in Canonsburg.
