Some 31% of Americans approve of Trump's performance in office, down a percentage point from two weeks earlier and the lowest level in either of his presidential terms, the four-day poll showed.

Asked which party they would vote for if the congressional elections were held today in what is known as ‌a "generic ⁠ballot" question, some 47% of registered voters in the nationwide poll picked Democrats, and 35% chose Republicans. The 12-point Democratic advantage was the widest over the current election cycle and could bolster Democratic hopes of seizing control of the US House of Representatives and the US Senate.
