Why is Russia insisting on immediate elections in Ukraine?

According to Igor Novikov, Russia's demand for immediate elections in Ukraine is a strategic attempt to conquer the country through political manipulation rather than military force. With half of Ukraine's population abroad and the other half on the front lines, the chaotic situation would enable Russia to easily stage the election process. This would allow them to install a Russian puppet government, effectively taking control of Ukraine without needing to continue the military campaign. Novikov explains this as Russia seeking 'an easier manner' to conquer Ukraine without having to 'return with tanks and weapons in two years time.'
