Here is a potential playbook, that has been used before, and might be used again, to replace a Democracy with a Dictatorship:
1. Create a distrust of the Press
2. Drive people to get news from non-traditional sources
3. Fill those sites with un-censored propaganda
4. Target your appeal to people who have guns, private people, plus police and military
5. Create a fear of a boogeyman, such as "communism" that the country must be saved from, and treat it as an imminent danger
6. Create a distrust of elections
7. After the election, challenge the results
8. Contest the election, demonstrating no evidence in court, and filing primarily frivolous lawsuits with untenable legal positions of no merit
9. Intend and expect to lose all those lawsuits, to prove that the courts are unfair, and the legal system can't be trusted
10. Replace top military leaders with people who are 100% loyal, and who you can trust completely
11. Eliminate any top military leaders who oppose using the military against civilians
12. Encourage "wild protests" (not to be confused with "peaceful protests"), and hope said protests lead to rioting nationwide
13. Declare martial law, and use the military to suppress the riots and re-establish order
14. Suspend the Constitution, and remain President "until such time as new, fair elections can be held" under the sole control of the ruling party.
Any similarity to real events is hopefully imagined.....
