The new Hotline poll, taken 3/29-4/1/07 finds approval at 35% and disapproval at 61%. The AP/Ipsos poll done 4/2-4/4/07 has approval at 35% and disapproval at 62%.
These move the approval trend estimate to 33.8%, well within the range of recent variation of the estimator.
There are still no recent outliers, so the dynamics appear unchanged since the last discussion of results here.
