TEHRAN (Press Shia Agency) – One year since US President Donald Trump's inauguration, a majority of Republicans under age 45 would want an alternative in 2020, a new poll reported.

A huge majority of Republicans less than 25 years old want the president to face a primary challenge, according to the latest Axios/SurveyMonkey poll.

Results of another poll showed that Trump has concluded his first year in office with the lowest approval rating of any first-year president in modern history.

That is according to polling by the NBC News/Wall Street Journal poll, which shows that Trump has averaged just a 39 percent approval rating since his inauguration on January 20, 2017. The survey was released on Friday.

Trump's approval rating is lower than his three immediate predecessors – Barack Obama, George W. Bush and Bill Clinton — at the same point in their time in the White House.

Fifty-seven percent of respondents have disapproved of the presidency of Trump.

In the history of the NBC/WSJ poll, Trump has scored the lowest first-year approval rating out of any modern president.

The previous low was held by former President Obama, whose first-year average stood 11 points higher than Trump’s, at 50 percent. Bush ended his ended his first year in office with 82 percent and Clinton came in at 60 percent, according to the NBC/WSJ poll.
