The new NBC News poll confirms that Biden is getting no bump — he’s at flat 40 percent approval — and it’s inflation that’s destroying his presidency:

Approval of Biden’s handling of the economy is declining as the cost of living has jumped to become Americans’ most important issue in the poll, displacing jobs and the economy, voting rights/election integrity and the coronavirus, which all topped January’s survey.

Sixty-two percent of respondents said their family incomes are falling behind the cost of living, 31 percent said they’re staying even, and 6 percent said their incomes are going up faster than the cost of living.

Asked whom or what they blame the most for increasing inflation, a plurality of Americans — 38 percent — pointed the finger at Biden and his policies. Republican respondents made up the bulk of those with that opinion.

Another 28 percent put the blame on the Covid pandemic, 23 percent attributed it to corporations that have increased prices, and 6 percent blamed the rising cost of goods and services on Russia’s invasion of Ukraine.

Asked which one issue should be Biden’s top priority — reducing inflation and improving the economy or working to end the war in Ukraine — 68 percent picked inflation/economy, compared to 29 percent who picked the war in Ukraine.
