These are the findings of a Reuters/Ipsos survey, Ukrinform reports.
The two-day poll that was concluded on Tuesday charted a sharp rise in backing for arming Ukraine, with 65% of the respondents approving of the shipments compared with 46% in a May poll.
At the same time, 81% of Democrats, 56% of Republicans and 57% of independents favor supplying U.S. weapons to Ukraine, according to the latest poll.
Also, the poll found that 76% of Americans believe that providing aid to Ukraine demonstrates to China and other rivals that the United States has "the will and capability to protect our interests, our allies and ourselves."
It is noted that the findings appeared to provide firmer backing for U.S. President Joe Biden's policy of assisting Ukraine in recapturing territory that Russia seized, as well as to strengthen the leadership positions of the Republican Party in Congress, which supports Ukraine.
The online Reuters/Ipsos poll was conducted nationwide, collecting responses from 1,004 adults, including 400 Democrats and 383 Republicans. A credibility interval is about 4%.
According to other sociological data, a significant majority of Americans - about 70 % - are more likely to support a candidate in next year's U.S. presidential election who will continue military aid to Ukraine.
