Well then APPARENTLY they were doing something right then that they're not doing now.
Because all the other polls were right there with them within the margin of error.
In their latest approval polls, they are way out of the bounds of the MoE.
more likely the OTHERS are doing something wrong
When you've got ten elements in a sample, nine of them show one result and the tenth shows another, the sole occurrence is normally the wrong one. Also, comparing election polling with issues polling is pretty meaningless. Rasmussen has a very good record on election polling. Their issue polling, on the other hand, has always been weak.
