Russia could turn on Putin as the nation's economic strength wanes and sanctions keep tightening, economists say

• Russia's economic strength is likely to wane this year, economists say. 
• Putin could lose support if Western sanctions make life more difficult for ordinary Russians. 
• Sanctions are likely to tighten if Joe Biden wins reelection in November, economists told Business Insider. 

Russia's economic resilience in the face of sanctions will be challenged this year, economists say, and they predict that Vladimir Putin could lose the support of the people if the West ramps up sanctions and makes life in the country more difficult.
