Who disapproves of Obamacare?

I was somewhat surprised by these numbers:

Fifty-three percent of the uninsured disapprove of the law, the poll found, compared with 51 percent of those who have health coverage. A third of the uninsured say the law will help them personally, but about the same number think it will hurt them, with cost a leading concern.

I wonder if any of this poll was conducted in Spanish, and if not whether that would have changed the results.  I found this interesting too:

Of the uninsured who said they were not likely to sign up by the deadline, fully half said it was because of the high cost. Twenty-nine percent said they planned to go without coverage because they object to the government’s requiring it, and 11 percent said they did not need health insurance.

And this:

Seventy-seven percent of the uninsured said they disapproved of the mandate, compared with 65 percent of those who already have health insurance.
