KMIS poll on Ukrainian attitudes to Lukashenko vs. protesters from:
It was carried out on 12-16 September, i.e. after the breakdown of Belorussian-Ukrainian relations following Lukashenko’s about turn on extraditing the Russian mercs to Ukraine.
Across the Ukraine, 31% support Lukashenko while 45% support the protesters. I would actually probably similar to figures for Belarus as a whole). But as expected, there are big regional differences, with 40-45% of the South and East supporting Lukashenko and 30% supporting the protesters, vs. 20% and almost 60%, respectively, in West Ukraine.
Most ideological groupings are similar to each other, with the major exception of Poroshenko supporters (almost universally pro-protester) and Boyko/Opposition Block supporters (overwhelmingly pro-Luka).
For comparison, in Russia, Lukashenko supporters constitute 46% vs. 17% for the protesters, according to this FOM poll, i.e. similar to results from S/E-Ukraine.
By far the biggest predictor of Russian political attitudes is age, reflecting a similar VCIOM poll I covered back in August. Whereas 68% support Luka vs. 9% protesters amongst 60+ y/o’s, this reverses into an outright plurality of 18-30 y/o’s supporting Luka, at just 19% vs. 30% who support the protesters.
