OK, I found the question. As a side note, it's journalistic malpractice to report these poll results without even including a link to the poll (as TheHill did).
The question asked was this:
Quote:
If you could grant Obama four more years and cancel this election altogether, would you?
The question asked of Republicans was this:
Quote:
If Donald Trump were to say that the 2020 presidential election should be postponed until the country can make sure that only eligible American citizens can vote, would you support or oppose postponing the election?
These are very different. The first question proposes a fantasy scenario in which the respondent just gets to choose what happens in the world. The second proposes a real-world scenario by actual powerbrokers and asks how respondent would react to it.
