Ok, so no obvious reason to why he is a potential tyrant or threat to democracy. The media that you read on a daily base have made plenty of comparisons between Hitler, who is responsible for 30m deaths and DT, who is a "convicted felon" because of tax fraud.
As for the claim you make towards his ethics, I understand your take but again doubt the people that you vouch for are any better.
Our governments sold themselves out over time to large companies and globalist movements. Its a good thing Trump and Vance want to address this and drain the swamp.
