I am not surprised "The Hill" is publishing the "Emerson College" poll on impeachment. No one else should be surprised either.
I know it is a poll, but, if one checks Emerson against most other polls it always is an outlier that seems to spin into the positive region for Republicans. It probably has something to do with the population of people within it's polling data.
I don't dismiss it. It is a good tool to realize where Republicans are in their thinking to ACHIEVE a winning strategy. For Dems and Independents and opposition Republican candidates, it can be opposition research. Ask, "Why is the darn thing an outlier?"
Polls, regardless of their source(s), should never be passively assessed as the ultimate authority. There are questions to ask and it lies in their methods, polling populations, and the FACTUAL DATA within the research.
