A new poll shows Donald Trump and Hillary Clinton locked in a dead heat in Missouri, just days after the Republican presidential hopeful opened a new campaign headquarters in Jefferson City and dispatched two veteran GOP operatives to bolster his support in the bellwether state.

Trump holds a 1-point lead — 44 percent to 43 percent — over his Democratic opponent among likely general-election voters in Missouri, according to a Monmouth University poll released Tuesday. Eight percent of voters plan to cast their ballots Libertarian nominee Gary Johnson in November, while 5 percent remain undecided.

While Trump leads Clinton by 13 percentage points among white voters, his edge narrows among independents. The billionaire businessman garners 40 percent support among independent voters, versus 35 percent support for Clinton and 14 percent for Johnson.

Interestingly, Trump is polling better among white women in Missouri than he is among white men despite months of polling that has shown him lagging behind Clinton among female voters, while maintaining strong leads among men. Currently, 54 percent of white women support him versus 45 percent of white men.

Clinton continues to carry a significant advantage among black, Hispanic and Asian voters, leading Trump by more than 60 percentage points — 78 percent to 13 percent. The former secretary of state is also seen by a majority of voters (53 percent) as the better candidate to handle race relations, sending a blow to Trump, who has spent the last several days campaigning for the African-American vote.

Fewer voters in Missouri believe Trump and Clinton are "looking out for the little guy," than those who say they are not concerned with the plight of the middle class. Only 38 percent of respondents said Trump would do a good job paying attention to average Americans as president, while 40 percent said Clinton would.

While Missouri has voted for the Republican nominee in the last four presidential elections, Trump campaign officials in the state have said they consider it a battleground.

The Monmouth University survey of 402 likely voters in Missouri was conducted Aug. 19-22. Results contain a margin of error plus or minus 4.9 percentage points.
