‘He’s dug a pretty serious hole here’: Ron Brownstein explains Trump’s approval ratings

After winning a plurality of the popular vote in November, Donald Trump’s approval rating has plummeted to 41% - the worst of any president in his first 100 days in 70 years - according to a new CNN/SSRS poll . His approval on the economy — a key to his longtime political viability — is at its lowest-ever level at 39%. Only 35% approve of Trump's approach to inflation, the same number who back him on tariffs.
