Well the obvious hipocrasy of the republicans with respect to the appointment of a supreme Court judge in an election year really does not lead to increase people trust in democracy. I encourage you to listen to the talks by republican senators when they blocked Obama from appointing a new Supreme Court judge 9 month before the election and how they are talking now (less then 3 months before an election). Particularly damning are lindsey graham's statements, he literally said as late as 2016 supreme court judges should not be appointed in an election year, we (as republicans) will not do it. You can hold my words against me. And now he supports Trump appointing a new judge. The blatant disregard for any accountability, not calling out (and support) of corruption and fascist rhetoric from trump certainly undermines democracy, if it will lead to civil war is a different question. However the rethoric from some parts of the republican party are definitely going in that direction. Hell some parts are actively supporting qanon.
