Polls tend to fly in formation, tightly grouped, within a margin of error. A poll's institutional bias will add to the spread, e.g. Rasmussen having a GOP tilt. But in the fog of statistics, every so often, one poll peals off from the rest.
Will others follow, or is that poll lost in a morass of sampling error? On Friday the ABC/Washington Post poll left the pack with Trump disapproved by 60% and approved by 38%. But today it is no longer alone. IBD/TIPP has Trump dropping to a 36% approval with a 58% disapproval.
If other polls join, the midterms could have long term consequences for the GOP.
