Here is a list of the ways Trump is trying to steal the election:
Tamping down and misrepresenting information from his own intelligence agencies on Russian election interference to help him get reelected in 2020. https://www.forbes.com/sites/alisondurkee/2020/09/02/trump-administration-blocked-intelligence-russian-interference-influence-election-biden-mental-health/#61d21b4921e9
Overseeing the installment of a loyalist with no experience as Postmaster General, one who, just months before an election in a pandemic, cut funding and overtime hours and removed mail sorting machines from mostly Democrat majority states. https://www.nbcnews.com/think/opinion/trump-dejoy-s-usps-meddling-isn-t-over-why-are-ncna1237479

Forming contingency plans to encourage Republican-controlled state legislatures of swing states to select electors for him even if voting counts show Biden has won.
Advising supporters in North Carolina to vote twice, supposedly to “test the system,” thereby encouraging his followers to commit felonies and disrupt the election process.
Priming his followers to engage in street violence by inciting social unrest amongst them using a range of provocations, including the claim that the only way he could lose he election is if it’s “rigged” and suggesting that the anti-police brutality, Black Lives Matter protests, only 7% of which have had incidents of lawbreaking by a tiny minority of protesters, were comprised largely of rioters, looters, and anarchists. https://thehill.com/homenews/administration/512424-trump-the-only-way-we-are-going-to-lose-this-election-is-if-the
Hiring 50,000 “poll checkers” to go to the polls ostensibly to prevent fraud but in actuality almost certainly to intimidate Democrat voters in various ways, including challenging their right to vote by use of bogus check-lists.https://www.independent.co.uk/news/world/americas/us-politics/trump-2020-vote-volunteers-polling-monitors-november-election-democrats-a9521011.html
Pushing for a quick replacement before the election for Supreme Court Justice Ruth Bader Ginsburg explicitly because he wants the Supreme Court to rule in his favor in legal challenges to ballot counting. https://www.yahoo.com/news/trump-pence-gop-supreme-court-2020-presidential-election-results-161405934.html
Vote early or vote in person. It’s your right.
