I'm not sure you can say he "hasn't read his own bill" here.
The exact quote-
"During the call, a blogger from Maine said he kept running into an Investors Business Daily article that claimed Section 102 of the House health legislation would outlaw private insurance. He asked: “Is this true? Will people be able to keep their insurance and will insurers be able to write new policies even though H.R. 3200 is passed?” President Obama replied: “You know, I have to say that I am not familiar with the provision you are talking about.”"
All he's saying is that he didn't see that provision in the bill. Not that he hasn't read the bill. At least, that's the way I'm reading it.
I'm not trying to be an apologist, I'm as against this thing as any other crap legislation I've seen down the pike in the past seven months.
