OK... Here's how it broke down in the warped mind of Limbaugh. Rush apparently read the mind of shooter Nidal Malik Hasan and found out that he went on his rampage because Obama said he would get American troops out of Iraq and hasn't done that yet. That's It... Really! Here is what he said verbatim:
... "we can almost say that this is Obama’s fault, because this guy said that he believed that Obama was going to get us out of Iraq and Afghanistan. Obama hasn’t done it, and that’s one of the reasons why the guy cracked."
Quite a stretch even for his drug addled mind. By the way wasn't it George Bush that got us into the Iraq war by choice? Just saying.
