Undermining Free and Fair Elections
Destroying Checks and Balances
Normalizing corruption
Flooding society with misinformation
To take it farther back...in the Federalist Papers, Madison wrote that factions pursuing their own agendas at the expense of the common good, the concentration of power in a single branch and the acquiescence of the other two, and an ill-informed public could readily combine to destroy our constitutional democratic republic (Hereafter, CDR).
Hamilton: Earlier today I wrote about rereading Federalist Paper #1, right there Hamilton wrote..."Of those men who have overturned the liberties of republics, the greatest number have begun their career by gaining the confidence of the people...” -- i.e., Demagoguery can lead to the end. Hamilton also saw incompetence as a detriment to the continuance of CDR -- the kind of thing one sees with Hegseth, Patel, Noem, Long, Bondi, and RFK Jr. In Federalist #29 Hamilton argues that a similar incompetence and coupled with the same type of misinformation that worried Madison could also threaten the CDR.
