U.S. President Donald Trump is losing his touch, and he's just in his second year of office.

According to the recent approval rating survey conducted by Gallup, Trump's approval rating went down further to 37 percent, two points down from his approval rating in December. Compared to the second-year ratings of other past presidents, Trump is the most unpopular head of state to ever grace the Oval Office.

Gallup compiled the poll results by doing a phone interview with over 1,500 adults with a margin of error of plus or minus 3 percentage points. His highest approval rating was 45 percent, which was deduced after he took office in January 2017.

The numbers weren't even a bit close to Trump's predecessors during their second year-term. During his second year in office in January 2010, Barrack Obama scored an approval rating of 49 percent. George W. Bush proved to be really popular, with an approval rating of 84 percent in January 2002. Bill Clinton garnered 55 percent in January 1994, and Geroge H W. Bush scored an 80 percent approval in January 1990.

 SurveyMonkey also did a year-long assessment of Trump's approval ratings, and the results were saying that his popularity within the white working-class women has deteriorated rapidly as his second year in office unfolds.

According to LA Times national political correspondent Ron Brownstein, "[H]is position has deteriorated among white women without a college degree. Last year he carried 61 percent of them. But in the new SurveyMonkey average, they split evenly, with 49 percent approval and 49 percent disapproval."

"His approval rating among non-college-educated white women never rises above 54 percent in any age group, even those older than 50. From February through December, Trump's approval rating fell more with middle-aged blue-collar white women than any other group," he added.

The gender gap in American politics is quite common, and although more and more working-class women are withdrawing their support for Trump, his popularity among men, especially non-college-educated white men over 50, is more or less maintained. Still, if the Presidents wants to win the re-election, he better make sure to win the support of all the demographic groups in the U.S.
