Poll reveals qualities voters are most uncomfortable with in their president. Democrats hardest hit.

What qualities do Americans value in their president? Most want a strong leader who shares their political worldview but is pragmatic enough to seek the common well-being of the nation. Others highly value demographic characteristics such as gender or race.

But a new poll reveals two qualities the majority of Americans do not want in their president — and it's not good news for the majority of 2020 Democratic presidential candidates.

What does the poll show?

According to a new NBC/Wall Street Journal poll, just 4 percent of registered voters are "enthusiastic" about socialists or candidates over the age of 75.

On the flip side, 43 percent of respondents said they are "very uncomfortable" with a socialist while 29 percent said they "have some reservations." Only 19 percent of respondents said they are "very uncomfortable" with candidates over age 75 while 43 percent said they "have some reservations."

Similarly, 33 percent of respondents said they would be "comfortable" with an elder candidate while just 21 percent said they would be "comfortable" with a socialist.

As far as age goes, two men considered front-runners for the Democratic nomination — former Vice President Joe Biden and Sen. Bernie Sanders (I-Vt.) — are both over 75. Biden is 76 and Sanders is 77.

Meanwhile, many other Democrats running for president support quasi-socialist policies, or at the very least, are trending more leftward in their politics toward ideas espoused by Rep. Alexandria Ocasio-Cortez (D-N.Y.), who considers herself a democratic socialist. Sanders, on the other hand, openly supports socialism.

What do voters most want?

According to the survey, registered voters would be most enthusiastic to vote for a person of color or a woman. Respondents said they have the least reservations about voting for white men, however.
