I doubt they'll pull it off. DEI is their latest boogeyman term for what the other side does. They have a new one roughly every election cycle.
During the Obama administration, it was "Cultural Marxism." Obama was a Cultural Marxist so he hated the US, hated the West, was trying to undermine it. His staff were all Cultural Marxists, etc., etc.
Last election it was "globalists." So Trump was a patriot nationalist and the libs were all globalists that wanted a New World Government and were going to allow UN tanks to roll into your town and impose martial law or whatever.
This time around it's DEI. DEI madness is what brings trannies to libraries, any time a nonwhite person does something they don't like, it's DEI that put them in that position, DEI is what made the Little Mermaid black, etc.
