On one hand, it’s Trump and Republicans and they’re gross. But it would be a bigger deal if they somehow skipped the 13th and 19th in a more purposeful way. Only including the original Bill of Rights in stuff like this isn’t an uncommon thing.
Although funny note, the 27th Amendment was actually proposed with the rest of the bill of rights, alongside another unratified amendment that would have pre-empted the problems we have in the House of Representatives caused by the Permanent Apportionment Act of 1929.
They should hold a parade to commemorate it.
