SOUTH ABINGTON TWP. — When it comes to fulfilling campaign promises, if elected, Donald Trump would apply the same techniques he's used on the campaign trail, his firstborn son said at a campaign event Saturday.

"I think he's going to be a disrupter," Donald Trump Jr. said. "And that's critical here because we need somebody who's going to disrupt things, because the same-old, same-old hasn't been working."

Trump played up his years as a youth attending The Hill School boarding school in Pottstown, later University of Pennsylvania for college, and frequent hunting and fishing trips to the mountains of Pennsylvania, as he stumped on his father's behalf.

When he was a boy, Trump watched his father as a committed businessman. Having passed the family business to his son, the elder Trump wants to use his business acumen to restore financial success and stability to America, his son said.

More than 100 people packed his father's campaign office along State Street. They chanted "Trump" as his Cadillac Escalade pulled into the parking lot.

Trump visited in advance of his father's appearance scheduled for 7 p.m. Monday — one day before the primary election — at Mohegan Sun Arena at Casey Plaza, Wilkes-Barre Township. Tickets are required to attend.

At his side, U.S. representatives Lou Barletta, R-Hazleton, and Tom Marino, R-Lycoming Township, pressed the crowd to mind the delegates they vote for Tuesday.

Pennsylvania Republicans will send 71 delegates to the Republican National Convention in July. Of them, only 17 are bound to vote for their districts' popular candidate. Out of 162 delegate candidates, 50 have promised to vote for Tuesday's top vote getter, according to a survey published Saturday by The Morning Call newspaper in Allentown.

The Trump campaign office is advising voters on which delegates have pledged to vote for them.

"He's not a rubber-stamper. He's got convictions, and he lets people know what he stands for," said Robert Sukel of Waverly, wearing a fire-engine red ball cap emblazoned with the Trump slogan, "Make America great again."

Watching from the back of the campaign office, Bill and Susan Rice of Tunkhannock said they believe Trump would relieve big corporations of their political power and restore it to the American people.

"I think he's going to change government," Rice said. "The way it's run now, the people don't have a say in anything and he's going to change all that, make it great again, make it our government again."
