How many times do I have to explain this crap - its very simple math. 
95% of blacks support him - that = about 10%  
55%-65% of hispanics support him  =  7%
Probably 35% of whites support him =  23-28%  
Then you have the "other" - which are fringe groups  = 6-8%
Obama also has a base 100% support of the parasite vote.  those that want the other 50% to pay more so they can live for free off the other half will always support the thief promising to rob the other 50% on their behalf.  
Its simple math 240.     
I'm not disputing your numbers.
I'm pointing out 46% of the US population still supports the guy.
In the middle of brutal lib legislation, a depression, insane UE... he's still at 46%.
God forbid things recover, we're attacked, or anything else happens to bump him up a few points.
Repubs should be kinda concerned and should stop patting themselves on the back for that brutal "fall" from 48% to 46% over the last, say, YEAR.  Put up a candidate that can win in 2012.  "Anyone but Obama" just won't beat him.
