More than half of US voters plan to reject Donald Trump in 2020 elections, poll says

About 52% of US voters plan to vote against President Donald Trump in next year's national election although he retains broad core Republican support, a new poll showed on Thursday.

"The latest Rasmussen Reports national telephone and online survey find that 42% of US voters say they are more likely to vote for Trump in the 2020 presidential election," the polling organisation said in a press release.

"But 52% are more likely to vote against him," Rasmussen said.

The polling agency said that at least 6% of US voters remain undecided.

"Among all voters who say they are likely to vote against the incumbent, 58% say their vote is more likely to be a vote against Trump than for some other candidate. 37% expect their vote to be more about the other candidate," the release said.

Some 75% of Republicans remains likely to vote for Trump again. However, 21% of Republicans are more likely to vote against him next year, the polling company said.

"Trump loses to Democrats by an 82% to 13% margin," it stated.
