"Without a doubt, Donald Trump's personal style was part of his appeal in the 2016 campaign", said Democratic pollster Fred Yang, who conducted the survey with Republican Bill McInturff told WSJ.
Trump's low approval rating, which dropped to 36 percent from 42 percent in April, could also be significant if it fails to improve in the next year.
There is a Democratic preference: Among all adults, 53 percent say they'd prefer to see the Democrats take control of Congress "to act as a check on Trump", vs. 35 percent who'd like to see the GOP retain control "to support Trump's agenda".
Democrats need to come up with a realistic, comprehensive plan to fix the problems with the ACA that everyone knows about - high deductibles, lack of options in some states, etc. - and they need to go on the air, on the House and Senate floor and on the road to sell it. Independents and soon-to-be disaffected Trump voters with health care concerns need an answer to the question, "Why should I vote for you?" Historically, the party in the White House tends to lose congressional seats in midterm elections. At present, based on FiveThirtyEight's poll aggregation, Trump is viewed favorably by about 39 percent of the American public, and unfavorably by about 56 percent.
People living in counties that helped elect Trump largely supported him on key issues like keeping jobs in America, dealing with North Korea and his response to the use of chemical weapons in Syria - 75 percent, 68 percent and 66 percent, respectively. Overall, 58 percent of voters say they are certain to vote next year, while 72 percent of strong Trump backers are certain they will vote. Seventy-five percent of respondents approved of his methods, while only 14 percent opposed them. More than half of voters said that Trump is not an influence on their decision.
The poll did not ask a generic congressional ballot question - an indicator often cited by party strategists - but recent polls show that voters favor Democrats over Republicans for Congress by between six and 10 percentage points when asked whom they would rather vote for. Of the 33 seats in that chamber being contested, 25 belong to Democrats or independents who caucus with them.
