A new poll by PRRI reveals rising support for President Donald Trump’s impeachment, with four in 10 Americans hoping to see the president removed from office.

The rise in support for Trump’s impeachment comes from Democrats – 72% of Democrats now say they think Trump should be removed from office, compared to just 58% in the last poll six months ago. Support for impeachment also grew among independents, from 27% to 38%.

The number of Republicans who believe Trump should be impeached has remained “virtually unchanged” since February, according to the report – only 7% want to see Trump thrown from the White House.

The report reflects the increasingly stark divide between Democrats and Republicans in how they view Trump’s potential impeachment, along with attitudes toward the investigation into the Trump campaign’s possible collusion with Russia to sway the 2016 election.

Further illustrating the party divide, the survey also found that 80% of Democrats believe Russia interfered in the election to help Trump win, while only 20% of Republicans agree. The US intelligence community has been unanimous in its assessment that Russia did indeed interfere.

Americans view Trump much less favorably than past Republican Presidents George W. Bush and Ronald Reagan. Ronald Reagan is considerably more popular and is viewed as the best representative of GOP principles and values.
