Donald Trump may need to temper his euphoria with officially being declared the presumptive Republican nominee.

Just hours after Trump was so anointed, a new CNN/ORC poll finds him trailing Democratic front-runner Hillary Clinton 54 percent to 41 percent with less than six months remaining before their, presumed, early November general election showdown.

Clinton's Lead in Poll Largest in Ten Months Some

The poll notes the 13-point margin is the largest Clinton has held over Trump since last July. Pollsters found the former secretary of state and New York senator is much more trusted than Trump on the issues many voters declare as the most significant.

Surveyors found Clinton is more trusted on the issue of immigration than Trump by a count of 51 percent to 44 percent. In addition, she is viewed as more trustworthy on terrorism (50 percent to 45 percent), healthcare (55 percent to 39 percent), income gap (54 percent to 37 percent), foreign policy (61percent to 36 percent) and education (61 percent to 34 percent).

The only metric Trump rated more favorably on was the question of who would fare better handling the economy, where he was favored by a margin of 50 to 45 percent.

On the overall issue of favorability, 49 percent of voters view Clinton positively, against 49 percent who have a negative image of her. By comparison, only 41 percent of voters see Trump in a positive light, against 56 percent who have a negative image of him.

Trump all but locked up the GOP nomination by recently winning the Indiana primary and forcing Texas Sen. Ted Cruz out of the race.

Pollsters found the bombastic New York City real estate mogul and Clinton would combine to represent the most disliked major party nominees in more than two decades.

The only other candidates to attracting less than 50 percent favorability in CNN polling heading into the general election were Mitt Romney in 2012 (44 percent) and Bill Clinton in 1992 (42 percent).

Most Voters Feel Underserved

Data also shows among Clinton's supporters 51 percent admitted it has more to do with denying Trump, while 57 percent of his supporters said the same about the former first lady.

Overall, just 24 percent of voters say they feel well-represented in Washington, with Democrats feeling that way by a more than 3 (35 percent) to 1 (10 percent) ratio over Republicans.

A recent Washington Post-Univision poll also shows Trump continues to struggle mightily with Latino voters with more than 80 percent of them insisting they have a negative view of the man who has vowed to deport more than 11 million immigrants.
