With the public impeachment hearings about to start regarding Donald Trump, we don't yet know whether he'll be impeached and removed or resign (like Nixon did). I doubt he'll resign. His ego and narcissism will probably prevent that. The opinion of most political pundits is that he will be impeached by the House, but not removed from office by the Senate (thanks to Republican senators).
I found this chart interesting. It is from the Gallup Poll. They questioned 1,506 adults between October 14th and 31st, and that survey had a 3 point margin of error (5 points for Independents, and 6 points for Democrats and Republicans). They compared Trump to Richard Nixon (right before he resigned to avoid impeachment).
Among all adults, 51% want Trump impeached and removed from office. That number was 58% for Nixon. Among Independents, the numbers for Trump (53%) and Nixon (55%) were very close. But there is a significant difference among Republicans and Democrats.
About 31% of Republicans wanted Nixon impeached and removed, while only 7% want that for Trump. About 71% of Democrats wanted Nixon removed from office, but an even larger 87% want Trump removed.
Frankly, I think it's remarkable that so many already want Trump removed, before any public hearings have happened. It took much longer and public hearings to get a majority wanting Nixon removed. Of course, Nixon wasn't as unpopular as Trump is before the public hearings.
