A poll conducted by KFF, a nonpartisan health research organization, has found that lower costs are the top priority for voters who identify as supporters of the Make America Healthy Again movement. The survey also found that 61% of all respondents said health costs will have a significant impact on their vote for the next Congress. This is expected to negatively impact Republicans' chances of maintaining control of Congress. The poll was conducted among a nationally representative sample of 1,343 U.S. adults and had a margin of error of plus or minus 3  percentage points. The Trump administration has been criticized for not adequately regulating chemical additives in food or pesticides in agriculture, and the poll found that 38% of respondents approved of vaccine policy and 46% of food policy.
