The Republican and Democratic nominees each get 46 percent of likely voters in a head-to-head contest in the latest Bloomberg Politics national poll, while Trump gets 43 percent to Clinton’s 41 percent when third-party candidates are included.
These new numbers "erase" the 6-point advantage Clinton had last month, Bloomberg notes.
Clinton's email scandal and health may have something to do with her struggling poll numbers. The image of her stumbling off the curb at the 9/11 memorial are still fresh in voters' minds and pundits have questioned whether she can "power through" all 90 minutes of Monday's debate, commercial break-free.
Still, with these question marks, the Bloomberg survey also showed that 49 percent of voters think she'll perform better than the GOP nominee.
The Clinton campaign is not happy with the fact that Trump is likely to be "graded on a curve" and given passing marks just for managing to not say something outlandish.
The presidential debate will air on CNN at 9 p.m. ET live from New York's Hofstra University and will be moderated by Lester Holt.
