When the poll is expanded to include Libertarian and Green Party candidates, McCaskill leads Hawley 44-40, but that is within the poll’s margin of error. 

McCaskill is facing a lopsided approval rating, with 41 percent of likely voters viewing her positively compared with 49 percent who view her in a negative light.

Hawley has a 36-36 favorable/unfavorable rating. However, 28 percent of likely voters are unsure or have never heard of him. 

However, the Missouri senator may be buoyed by the enthusiasm of her supporters. About 68 percent of her backers strongly support her, compared with 46 percent of Hawley’s backers who strongly support him.
