What do you mean builder.
Didn't you see the results ;-)
Seriously, I could imagine that in the actual cities of Luhansk and Donetsk, which have had 8 years of brainwashing and where there have always been some people who hanker after Russia, then probably some.
The rest of those regions: negligible I'd say, especially now.
Kherson and Zaporizhzhya: less than negligible.
It seems as though they intend to "annexe" the entirely of the four regions, despite the fact that they control none of them entirely, even Luhansk, barely half of Donetsk, about 60% of Zaporizhzhya, but not the city of Zaporizhzhya itself. So they are going to declare a part of Russia a city that they don't even control.
Utterly bonkers
Added to which, they also still occupy small parts of Kharkiv and Mikolaiv regions (for now)
It looks as though they are deploying draftees - up to 20,000 - to Belarus, possibly to open some sort of diversionary new front to the north.
More insanity.
