Whether this candidate be male, female, gay or African-American, U.S. voters will elect the Democratic candidate opposing president Donald Trump in the 2020 presidential election.

A new poll from NBC/WSJ shows Trump facing immense obstacles to his re-election bid, with 48 percent of voters saying they’d “definitely” or “probably” vote for the Democrat candidate as opposed to 41 percent who say they’d “definitely” or “probably” vote for Trump.

The poll also shows 58 percent of respondents don’t think Trump’s been honest and truthful regarding the Russia probe. It also revealed that 60 percent disapprove of his recent national emergency declaration to build a border wall with Mexico. Trump faces double-digit deficits among voters under 50, women and independents.

Trump’s standing is worse than that of George W. Bush and Barack Obama, both of whom led generically described opponents at similar points in their re-election bids. Bill Clinton trailed by a slightly smaller margin in January 1995 but went on to win a second term like Bush and Obama.

As can be expected, the top groups approving of Trump are Republicans (88 percent). Other groups that approve of the president rural residents (60 percent), whites without college degrees (60 percent), men (54 percent) and whites overall (54 percent).

The top groups that disapprove of Trump: African Americans (88 percent), Latinos (64 percent), women (61 percent), those ages 18 to 34 (57 percent), whites with college degrees (55 percent) and independents (51 percent).

College-educated white women favor whoever the Democrat presidential candidate is by 26 percentage points, while Hispanic voters will vote for the Democrat by 40 points. Two-thirds or more of American voters described themselves as either enthusiastic or comfortable with a presidential candidate who is gay, female or African-American.

The poll also found more problems for Republicans than Democrats as regards key issues. Fifty percent or more of Americans called the GOP stand “outside the mainstream” on climate change, abortion, health care and immigration.

Democrats were slammed for their stand on “fiscal issues, such as taxing and spending.” The poll showed 47 percent of respondents saying the Dems are “outside the mainstream on this issue." An identical 47 percent called Republicans outside the mainstream on fiscal issues.

Among voters, the most popular candidate will be an African-American (87 percent of all voters say they’re “enthusiastic” or “comfortable” with an African-American). A white man (86 percent) is the next more popular followed by a woman (84 percent), and someone from the LGBTQ community (68 percent, which is up from 43 percent in 2006).

The least popular is a Muslim (49 percent are enthusiastic or comfortable, up from 32 percent in 2015), someone over the age of 75 (37 percent) and a socialist (25 percent). The latter two qualities are bad news for Sen. Bernie Sanders, the frontrunner among the more than a dozen Democrats that have declared their candidacy for the presidency.

As for socialism, only 18 percent of all Americans say they view the term positively. On the other hand, 50 percent who see it in a negative light. Fifty percent of respondents had a positive view of capitalism as against 19 percent who did not.

One positive sign for Trump: his job performance has improved to 46 percent of Americans since the end of the government shutdown. But 52 percent of those polled still disapprove of his job performance. In January, 43 percent approved and 54 percent disapproved of Trump

According to the poll, 48 percent of all respondents say Special Counsel Robert Mueller’s investigation into Trump’s collusion with Russia has increased their doubts about Trump’s presidency, compared to 47 percent who say it’s given them no more doubts. It also shows that 66 percent of voters say they want Mueller’s findings to be released to the public.
