WASHINGTON, Aug. 13 (Xinhua) -- Seven in 10 American women aged between 18 and 35 years old are dissatisfied or angry about the Donald Trump's presidency, the highest percentage of any age group of women in the United States, according to a poll released on Monday.

Only 9 percent of them say they are happy with Trump in the White House, the CBS News-Refinery29 survey found.

Among this woman age group, 53 percent think Trump's policies have mostly hurt women, while 70 percent feel their rights and liberties are being threatened rather than protected by what's going on in Washington.

By more than three to one, younger women prefer the Democratic Party win control of Congress. More of these women identify as Democrats than Republicans in the first place, the poll showed.

However, it isn't certain that many of them will turn out, the poll revealed, citing this women age group is the least likely of any age group to say they will definitely vote in the 2018 midterm election: only 30 percent say they definitely will, far lower than among older women (76 percent say they will vote).

The top reason of these women who say they may not vote this year is not being interested in politics and elections (31 percent), followed by not feeling like their vote matters (19 percent), not liking the candidates running (14 percent), and being too busy (14 percent).

The CBS News-Refinery29 survey is conducted by YouGov which interviewed 2,093 U.S. female adults online between July 26 and 30.
