NBC/Marist Poll: Clinton 45% Trump 36%

They have Hillary Clinton ahead 45% to 36% with registered PA voters. 19% are undecided.
What’s more, this survey was done after FBI Director James Comey’s press conference when he announced he would not indict the former Secretary of State over her email practices yet also sharply criticized her conduct.
“The good news for Hillary Clinton is that she is still even or ahead of Donald Trump in these three critical states in the aftermath of the FBI’s report on her email controversy,” says Lee Miringoff, director of the Marist College Institute for Public Opinion, which conducted these three surveys. “The bad news for her is the contest has gotten closer in all of these states, and the issue does not seem to be going away anytime soon.”
While Quinnipiac had Clinton down in Florida and tied in Ohio, NBC/Marist had Clinton ahead in Iowa and also tied in Ohio.
When Libertarian Party nominee Gary Johnson and Green Party nominee Jill Stein are included Clinton’s lead dips just a bit. In a four-way race Clinton receives 43%, Trump 35%, Johnson 8% and Stein 2%.
NBC/Marist surveyed 829 registered Pennsylvania voters from July 5th to 10th. The margin of error is +/-3.4%.
