News of a poll post the impeachment:
Over half of Americans (58%) say that Trump should have been convicted, which tracks with the 56% who said the same last week before the 57-43 Senate vote to acquit left Trump free to possibly run for office again. Last year, after Trump was acquitted in his first Senate impeachment trial, Americans were evenly split on the outcome, with 49% approving of the Senate's judgment and 47% disapproving, according to a Monmouth University poll....
The seven Republicans, who make up 14% of the GOP conference in the Senate, mirrors the 14% of Republicans nationwide who believe Trump should have been convicted and barred from holding future office in the poll, which was conducted by Ipsos in partnership with ABC News using Ipsos' KnowledgePanel.
I had to check again - how popular was the idea of Bill Clinton's impeachment back in the day. It was never very popular at all, as noted in this Gallup article written about Trump's first impeachment:
Americans' support for the Senate convicting Clinton in 1999 was much lower than current support for convicting Donald Trump. Gallup's Jan. 22-24, 1999, survey (one of a number we conducted while Clinton was on trial) found 33% of Americans in favor of Clinton being found guilty and removed from office, while 64% were against. Our latest survey on Trump shows 46% in favor of his conviction.
In the 1999 survey, Clinton's job approval rating was 69%, much higher than Trump's current 44% approval. So, the lower support for Clinton's conviction went hand in glove with his approval rating: 64% were against conviction compared with his 69% approval rating, and 33% were in favor of conviction juxtaposed against a 29% disapproval rating.
Thus, as is the case now for Trump, Americans' views on Clinton's impeachment largely reflected their overall assessment of the job he was doing more generally. Clinton had a high job approval rating and a concomitantly low "convict" rating; Trump's approval is lower and his "convict" rating higher.
