Nearly half of Americans believe that U.S. President Donald Trump will win a second term in office, according to a recent poll.

The poll revealed Sunday (local time) by CNN shows that 46 percent of responders said they think Trump will stay in the White House for four additional years, while 47 percent said he won't.

In a poll conducted in March, only 40 percent said they were positive about his victory.

The survey also shows that support for Trump serving a second term is growing across party lines.

Increases were shown among men (8 points), independents (from 39 percent in March to 47 percent) and those who are enthusiastic about voting in this year's midterm election (from 37 percent in March to 46 percent).

About 74 percent of Republicans and Republican-leaning independents said they would like to see Trump nominated in 2020, while 21 percent said they would prefer a different candidate.

Among Democrats, former Vice President Joe Biden is emerging as a leading candidate who could challenge Trump.

Biden was chosen by Democrats and Democrat-leaning independents as the top pick among 16 candidates.
