Poll shows Clinton close, but Sanders ahead of Trump in Pa.

As Hillary Clinton emerges as the presumptive Democratic presidential nominee, a new poll of Pennsylvania voters finds her and Donald Trump in a tight race, with Bernie Sanders showing a substantial lead over Trump.

The survey by Public Policy Polling finds Clinton and Trump tied at 44 percent in Pennsylvania. When Libertarian Gary Johnson and Green Party candidate Jill Stein are included, the results are Clinton 41 percent; Trump with 40 percent; Johnson at 6 percent; and Stein with 3 percent.

Sanders leads Trump, 51 to 39 percent, in a head-to-head match-up. He leads Trump 45 to 36 percent when the other candidates are included, with Johnson taking 5 percent and Stein 1 percent.

It’s clear Clinton will be the party’s nominee, but Sanders and his supporters will cite surveys such as this one as evidence super delegates should swing his way.

The poll offers evidence Clinton can build a strong lead over Trump if she unifies the party.

Among those who support Sanders in the match-up against Trump, 72 percent said they’d support Clinton in the general election. Ten percent would go to Trump, 6 to Stein, 4 to Johnson, and 9 remain undecided.

The Public Policy Polling analysis says if Clinton can get half the uncommitted Sanders voters, she’ll have a 47 to 41 percent lead over Trump.

The poll shows Pennsylvania’s U.S. Senate race close. Incumbent Republican Pat Toomey holds a 41 to 38 percent lead over Democrat Katie McGinty, with both candidates suffering from relatively high negatives among voters surveyed.

The survey was conducted June 3-5, as the furor over Trump’s remarks about the judge in the Trump University case was developing.
