Foreign states, more specifically China, could use covert and overt measures to sway votes from President Trump.

Already, there was an incident in June, when Chinese video app TikTok saw users band together and falsely reserve tickets for President Trump's rally in Tulsa, Oklahoma, which resulted in an embarrassingly low turnout. As a result, the administration when on the offensive against the app and has since signed an executive order to ban it next month. 

China could also be attempting to undermine the election by sending counterfeit driver's licenses to the U.S. So far, the Customs and Border Protection (CBP) officers working at Chicago O'Hare International Airport have intercepted close to 20,000 counterfeit U.S. driver's licenses shipped from China this year, reported FOX 5 New York.
