>> Voters head to the polls in the second major round of primaries on Tuesday in Oregon, Idaho, Nebraska and Pennsylvania. A state that's become crucial to democrats plan to retake control of the House in this year's midterm elections. Five Republican seats are up for grabs in Pennsylvania with redistricting retirements and resignations making many of the State's districts much more competitive.
Democrats need a net total of 23 seats across the country to assume the House majority, making Pennsylvania key to the party's strategy, and the field of candidates is huge. Some 81 candidates are running for 18 congressional seats in the state, including ten democrats in a single race. The most closely watched contest is for Pennsylvania's 15th congressional district.
Representative Charlie Dent, one of the few remaining moderate Republicans in the House, is retiring. The three top contenders from the Democratic party vying for his seat are Greg Edwards, a pastor backed by a progressive, Senator Bernie Sanders. Susan Wild endorsed by the abortion rights group Emily's List, and John Morganelli, who opposes abortion rights and has been supportive of President Trump's hard line immigration policies.
