Trump Hits a New High in the GOP Race; Against Clinton, It's Outsider vs. Experience (POLL)

— -- Donald Trump has reached a new high in support for the Republican presidential nomination in a new ABC News/Washington Post poll, drawing on GOP support for his proposed ban on Muslims along with his powerful outsider credentials. Ben Carson’s cratered, while Ted Cruz has advanced to join the double-digit club –- but with Trump now unrivaled for the lead.

That said, Trump slightly trails Hillary Clinton in a general election matchup, by 6 percentage points among registered voters, expanding to 13 points among all adults. And a broad 69 percent of Americans express anxiety at the thought of Trump as president, with half saying it makes them “very” anxious. Clinton makes far fewer anxious, albeit 51 percent.

Trump has 38 percent support for his party’s nomination from Republicans and GOP-leaning independents who are registered to vote, up a slight 6 points from last month, entirely among men. He’s added concerns about terrorism to his existing anti-immigrant, political outsider credentials -– all pressing items in his party, but less so outside of it.

Tested against his top rivals in this poll, produced for ABC by Langer Research Associates, Trump has gained 8 points in trust to handle terrorism and 7 points as the strongest leader, as well as 9 points in being seen as likeliest to win in November. He holds vast in-party advantages on all three items, and on handling immigration as well.

Critically, leaned Republicans by 58-37 percent say they’re looking for someone from outside the existing political establishment rather than someone with political experience. Trump’s support among the majority favoring an outsider soars to 50 percent, compared with 21 percent among those putting a priority on experience. It’s the central feature of the Trump phenomenon.

A challenge is what may happen outside the party. Among all adults, the tables turn – 37 percent are looking for an outsider, while more, 57 percent, prefer a candidate with political experience. Among Democrats and Democratic-leaning independents, preference for experience soars to 76 percent, with just 18 percent looking for an outsider.

In a statistical analysis testing the strongest independent factors in support for Clinton or Trump in a hypothetical matchup, her single biggest advantage is experience, and his single biggest advantage is being an outsider – factors that, remarkably, are even stronger than partisanship and ideology. Just within the GOP contest, the same analysis finds that Trump’s outsider status is his single biggest asset.

Republicans

Trump’s gain in support this month came among men, up 17 points, leading to the re-emergence of a broad gender gap: He’s backed for the nomination by 47 percent of men vs. 28 percent of women. He also remains strongest among less-educated and lower-income leaned Republicans, with 42 percent support among those who lack a college degree and 50 percent among those with incomes less than $50,000. Those can be low-turnout groups, a potential risk for Trump.

Trump-Clinton

There’s a continued split between the parties in top issues. Most leaned Republicans cite terrorism or the economy, 38 and 29 percent, respectively, with other items (health care, immigration and tax policy) in the single digits. Among leaned Democrats, the economy clearly is first, cited by 38 percent, with health care and terrorism next, at 19 and 17 percent.

The choice of issues matters in a hypothetical general election matchup. Among those most concerned with the economy (a Democratic-leaning group, as noted), 58 percent prefer Clinton vs. 36 percent for Trump. The margin flips among those most concerned with terrorism (a more GOP group), 61-33 percent, Trump-Clinton.

Clinton’s six-point advantage among registered voters is significant at the 90 percent confidence level, albeit not at the customary 95 percent. That’s a better result for her than her +3 vs. Trump, 46-43 percent, in a matchup in September.

There are other divisions – a 14-point advantage for Trump among whites, for example (Mitt Romney won this group by 20 points) and a 52-point lead for Clinton among nonwhites (Obama was +61). Clinton, further, leads by 22 points among those with post-graduate degrees, a group Obama won in 2012 by 13 points. Clinton and Trump are about even among those who lack a college degree.

Trump, notably, has gained 9 points among those preferring a candidate from outside the political establishment, from 64 percent in September to 73 percent now. Clinton’s lost 7 points in this group, from 25 percent to 18 percent, but wins 72 percent of those who favor a candidate with experience. And at least at the moment, as noted, that’s the factor driving the 2016 race.
