Pennsylvania Primary Election Polls 2016: Trump And Clinton Maintain Double-Digit Leads Ahead Of Tuesday Voting

Businessman Donald Trump and former Secretary of State Hillary Clinton maintained double-digit leads in Pennsylvania ahead of primary voting Tuesday, according to a new NBC News/Wall Street Journal/Marist poll published Sunday. The demographics of the poll were in line with trends in the past several months, with men without college degrees voting for Trump among Republican candidates and African-American voters poised to choose Clinton in the Democratic camp.

In the Republican camp, Trump saw 45 percent support from likely Republican voters in the state, followed by Texas Sen. Ted Cruz with 27 percent and Ohio Gov. John Kasich with 24 percent. As the spread between Trump and Cruz has narrowed nationwide — with Trump down several points to a 10.5 percent spread according to RealClearPolitics, which takes the average of recent polling data — Trump has increasingly accused the system of being “rigged,” saying the GOP delegate system is unfair.

"Ted Cruz has no chance of winning this without bribing the delegates. That's his game at this point," Trump's son Donald Trump Jr. told CNN Sunday, echoing his father's statements throughout the week that Cruz was trying to cheat his way to the nomination by gaming the delegate system.

Coming off of a 16-point win over Vermont Sen. Bernie Sanders in the New York primary last week, Clinton is poised to clinch another state, as the prospect of a Sanders nomination has grown dimmer. Clinton held a 15-point lead over Sanders in Pennsylvania, seeing 55 percent of support compared to Sanders’ 40 percent indicated by the same poll.

Despite Clinton’s delegate lead continuing to widen, many Sanders supporters have said they will not support the former Secretary of State if she were to win the nomination, vowing to write in Sanders’ name, in what has been dubbed the “Bernie or Bust” movement.

The poll was conducted in April among 3,006 residents and 2,606 registered voters, with a margin of error of plus or minus 1.8 percent and 1.9 percent for the two respective groups.
