9/15/16, "Trump Widens Lead Over Clinton," Monmouth University Poll

"Donald Trump now has an 8 point lead over Hillary Clinton in the battle for Iowa's electoral votes, according to the Monmouth University Poll.  He held a slimmer 2 point edge in July. In the race for U.S. Senate, incumbent Chuck Grassley maintains a double digit advantage over Democratic challenger Patty Judge.

Among Iowa voters likely to participate in November's presidential election, 45% currently support Trump and 37% back Clinton.  Another 8% intend to vote for Libertarian Gary Johnson, 2% say they will support Green Party candidate Jill Stein, 2% say they will vote for another candidate, and 6% are undecided. Trump's current standing is similar to his 44% share two months ago, but Clinton has lost support since July when she had a 42% vote share.

Among self-identified Republicans, 81% support Trump, which is down from 87% in July. Clinton has improved her standing among Democrats from 86% two months ago to 91% in the current poll.  Trump has been able to increase his overall lead, though, by improving his share of the independent vote. He now leads Clinton 44% to 29% among independents, compared to a much narrower 39% to 35% edge he had in July.

Nearly half (48%) of Iowa voters under age 50 currently support Trump compared to 33% for Clinton, 10% for Johnson, and 4% for Stein or another candidate. Two months ago, the under 50 vote split 51% for Trump, 32% for Clinton, 7% for Johnson, and 3% for another candidate. In Monmouth polls conducted nationally and in other states, Clinton has had the advantage with younger voters.

Voters age 50 and older are almost evenly divided between the two major party nominees. Currently, Trump has the support of 42% of this group, Clinton has 41%, Johnson has 6%, and other candidates have 4%. In July, Clinton actually had an advantage among voters age 50 and older, with 50% support compared to 38% for Trump, 4% for Johnson and 1% for other candidates.

Trump (42%) and Clinton (43%) are basically tied among voters with a college degree while Trump leads 47% to 34% among those without a college education. In July, Clinton had a 46% to 34% edge with college graduates while Trump had a 50% to 40% lead among those without a college degree.

"Iowa is one of the few places where Trump has been able make inroads among voting blocs that generally support Clinton," said Patrick Murray, director of the independent Monmouth University Polling Institute....

Turning to the Hawkeye State's U.S. Senate race, six-term incumbent Chuck Grassley has nearly doubled his prior lead over former Lieutenant Governor Patty Judge. The race now stands at 56% for Grassley and 39% for Judge, with 2% supporting other candidates and 3% who are undecided. The incumbent held a 52% to 42% lead in Monmouth's July poll.

Grassley's electoral strength is built on a strong job performance rating from Iowa voters - 58% approve and 31% disapprove of the job he has done in Washington....

The Monmouth University Poll  was conducted by telephone from September 12 to 14, 2016 with 404 Iowa residents likely to vote in the November election. This sample has a margin of error of + 4.9 percent. The poll was conducted by the Monmouth University Polling Institute in West Long Branch, NJ."
