Western Ukraine is fiscally conservative
Eastern Ukraine is socially conservative
It's not true. Both parts are socially conservative and fiscally liberal, as another countries of former USSR. Main differences are preferences in foreign politics (Western - EU, East - Russia), religion (Western - Ukrainian Orthodox, Greek-Catholic, Uniats, Eastern - Russian Orthodox), language (Ukranian for the West, Russian for the east) and more widely - cultural differences.
It's an inside joke, someone answered that to that very question years ago.
