A month ago we were celebrating -17.  It is a dead cat bounce.  
I am mostly haunting a different board these days.  I am starting to see a break from the libs over there.  I think in another short time, we will see them start to pile on too.
The Strongly approve numbers will never go below 15.  Ever.  He has a unbreakable baseline there.  Getting below 20 would be a sign that even he couldn't ignore, but I think from what I am seeing on the other board, he might break that by mid spring.
The jobs market is really messed up.  I think we will see the unemployment numbers jump too.  As that continues, we will see a continuous increase in seriously disapprove. 
For now, getting him to 30 will be a game of "patience, grasshopper."
