That poll has 74% support for "Deporting immigrants who are here illegally and have committed crimes".
It does not ask about "Trump's Deportations". I support deporting criminal immigrants. I even support deporting those with no criminal record who are here illegally (with some caveats). I don't support sending innocent people to brutal slave labor in a country not their own.
Supporting "Deporting immigrants who are here illegally and have committed crimes" is not the same as supporting "Trump's Deportations".
