Seven in 10 Americans saw Donald Trump unfavorably in a new ABC News/Washington Post poll — up 10 points in just the past month to a new high since he announced his candidacy for president. But Hillary Clinton reached a new high for unfavorability as well, 55 percent.

The results illustrate the striking challenges facing both candidates, cementing their position as the two most unpopular presumptive major party nominees for president in ABC News/Washington Post polling dating to 1984.

Trump’s numbers reverse a boost he received after securing the Republican presidential nomination, from 37-60 percent favorable-unfavorable in mid-May to 29-70 percent this month, after a week in which he took sharp criticism for suggesting that he was being treated unfairly by a federal judge because of the judge’s Mexican heritage.

Trump’s unfavorable score is a point below his highest on record, 71 percent in late May last year, just before he formally entered the presidential race June 16. His decline in favorability in the past month was broadly based across groups.

Interviews for this survey, produced for ABC by Langer Research Associates, were conducted Wednesday through Sunday, almost entirely before the terrorist attack in Orlando and the candidates’ subsequent comments on the tragedy.

Clinton, while less poorly rated than Trump, has troubles of her own, with no bounce in favorability after clinching the Democratic contest last week. From a 44-53 percent favorable-unfavorable rating last month, she was at 43-55 percent this month. While that’s within the margin of sampling error, it’s Clinton’s highest disapproval rating on record, in polls dating to her first appearance on the national stage in March 1992.
