Deranged Trump Supporter
A person who is suffering with DTS, also known as Deranged tRump Syndrome, possibly due to brain atrophy or just run-of-the-mill poor judgment.
The sad sack of a person I spoke with at the post office yesterday was clearly a Deranged Trump Supporter because he was desperately trying to articulate at least one example of something 45 had done well for the U.S. and he was wearing one of those pathetic red Make America Gag Again caps.
