>>Curious that he never mentions the outrage over illegal immigration.<<
that's not the main thing that people site - the study I looked at listed immigratio fourth behind Iraq, Gas prices, the economy(and yes I know that ridiculous) and then immigrations.
My three main concerns don't even make the list - terrorism, individual rights and the deficit.
A poll conducted by whom with what agenda?
Problems in Iraq would not drag his JA below 40. The reason so many on this thread say it the border problems that's dropped his JA so low is because he's alienated his base with his obstinate insistence on a temporary worker program, and THAT'S the reason his JA is running in the low 30s.
Only fools without reasoning skills would blame the President for high gasoline prices. That means only Dimocrats, who already are included in the job disapproval ratings, so that's not a significant factor in his JA dropping well below 40, IMO.
