Made-up crap used to justify putting Christians in concentration camps.
I have to say the only other time I heard of “Dominionist” was when Bachman was running in 2012. Apparently, the Left (PAGANs-People Against God And Normalcy) made up the term based on Bachman mentioning having a Christian “world-view.” Apparently we cannot have a world-view based on our faith, that to them is a theocracy and a march to world domination. Pure fantasy created by the PAGANs.
The only other time I have heard of “The Dominion” was in Star Trek Deep Space Nine and they were shape shifter aliens...very much like the PAGANs are:)
