Amid Europe’s largest land war since World War II, 7 in 10 Americans expressed low confidence in President Joe Biden’s ability to deal with Russia’s invasion of Ukraine in a new NBC News poll, and 8 in 10 voiced worry that the war will increase gas prices and possibly involve nuclear weapons.

And during the nation’s largest inflation spike in 40 years, overwhelming majorities said they believe the country is headed in the wrong direction and disapproved of the president’s handling of the economy.

Those are some of the major findings of the new national NBC News poll, which found that Biden’s overall job approval rating had declined to 40 percent, the lowest level of his presidency.
