Video: Ron Brownstein explains why trump ‘dug a pretty serious hole’ amid 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. CNN Senior Political Analyst Ron Brownstein joins CNN Newsroom to explain why the president’s ratings tumbled.
