I think this is his lowest approval yet.
He was at -14 on 8/23.
Close—he’s been -14.
Actually he has hit 27% approve several times. Here is the history chart.
He got 26% a few days back, but yes this is pretty low. The overall trend is down.
I don't expect to see his "strong approvals" to get much further down, since we're approaching his percentage of core supporters. It is nice to see his overall approval being -6, which is close to the lowest (-7 on 8/31).
One phenomenon that will be seen increasingly is that strong disapprovers will be more likely to voice criticism in public with reduced probability of strong approvers screaming at them for disrespecting The One. This will further erode Obama's image among those with no strong opinion.
