Biden’s boost amounts to “a pretty impressive rebound in Biden’s overall support,” said political scientist Lara Brown, a professor at George Washington University. Compared to mid-February,  the percentages of Democrats and independents who approve of the president gained 10 points or more. 
 
For months, enthusiasm for Biden had slipped even “among his own partisans,” Brown said, but the public in the U.S. has found common ground over Russia’s war in Ukraine. This bump also comes at a time when confirmed coronavirus infections have plummeted nationwide and unemployment has shrunk. 
 
“Democrats are rallying behind him,” she said, with nine out of 10 saying they back Biden in this latest poll.
 
In his State of the Union address, Biden denounced Putin’s actions in Ukraine.
 
“Throughout our history we’ve learned this lesson: When dictators do not pay a price for their aggression, they cause more chaos,” the president said. “They keep moving. And the costs and threats to America and to the world keep rising.”
 
More findings from our latest poll:

• About half of the U.S. public – 52 percent – said they support how Biden is handling the situation in Ukraine. Two weeks ago, when Russia had yet to invade, that number was much lower. Roughly a third said they approved of his leadership on the looming crisis.
• Eight out of 10 U.S. adults support the economic sanctions targeting Russia, and a slightly smaller majority is willing to go a step further – 69 percent said they support the sanctions even if they result in higher energy prices at home. This poll came before Biden announced a ban on Russian oil exports.
• People also fear escalating tension and Russian retaliation. Seventy percent of U.S. adults said they are concerned that Russia’s war in Ukraine could lead to nuclear warfare. And 78 percent are worried about Russian cyberattacks against the U.S. and a broader war spreading across Europe.

Up until today, there was a key area missing from the escalating sanctions against Russia: energy.
 
That changed today when Biden announced a ban on Russia oil imports to the U.S. The move answered pleas from Ukrainian President Volodymyr Zelensky for Western leaders to cut off the imports.
 
Europe’s dependency on Russia, which is the largest provider of natural gas to the continent, is also a factor in this situation. Europe relies on imports for 90 percent of its gas and 97 percent of its oil products, the Associated Press noted. The U.K. – no longer a part of the EU – pledged to phase out Russian oil by the end of 2022.
 
But will the rest of Europe join?
 
Considering the continent’s dependency on Russian oil and gas – not any time soon.

But today, EU officials announced their “REPowerEU” plan, which seeks to reduce consumption of Russian gas by two-thirds before the end of the year. The European Commission released a Q&A about the joint action here.
 
EU officials are expected to discuss the plan at an emergency summit Thursday in France, CNN reported.
 
More on Ukraine:

• Watch: In Biden’s announcement today about the ban, he also warned that U.S. gasoline prices will rise further.
• One Big Question: Now that there is a U.S. ban on Russian oil, what could that mean for Russia and the world? Remember: The U.S., unlike Europe, isn’t deeply reliant on energy it imports from Russia. In other words, a ban would be much more effective if European nations joined the embargo. At the same time, a ban would be much more painful for Europe.
• Explainer: There are growing calls for the U.S. and NATO to establish a no-fly zone over Ukraine. But what is a no-fly zone, and how would it work? So far, Western leaders have rejected the idea. Experts have also warned that it would broaden the conflict.
• A Closer Look: How did we get to this moment? The NewsHour's Ali Rogin looks at the history of Ukraine and its people's road to political independence.
