re: Why would Russia rather have Trump as President

They really don't care who is president. Oh sure, they could play any of the Democrats like a fiddle but that is not their real goal. Their goal is to push the political divide in this country further and further apart and the best way to do that is to put the idea into the Democrats head that they are trying to help Trump get re-elected. The Democrats are more reactive and less rational so they are easier to manipulate.
