Rasmussen highly overstates Trump and GOP in general.
There was a time I trusted them, but since ownership changes they are clearly a more activist organization than a polling one.
The best poll they had was one where they asked the same people over and over throughout time their choice. So you for a real good indicator or trends as the polling sample was the same every time.. so as long as the original sample group was reasonably random you got very very good indicators.. I don’t know if they still do that or not
Richard Barris is a good pollster. I trust his polls over all others.
